Fiend Warlock Build Guide – Fiendishly Powerful – 2024 Update

For all D&D guides on Nat1gaming, they only use the main sourcebooks (2024 Player’s Handbook, Tasha’s Cauldron of Everything, Xanathar’s Guide to Everything) as well as Strixhaven: A Curriculum of Chaos (mostly for Silvery Barbs) as those tend to be the most commonly used books at tables. Always be sure that if you’re following a guide that you’re adhering to your tables rules about what sourcebooks you are allowed to follow. Furthermore, be sure that you’re using the most current edition of the rules, especially as some 2024 Player’s Handbook rules are updates on Tasha’s or Xanathar’s rulings.

Any spell, class, feature, or other game item that is linkable on this website is covered by the 5th edition Open Games License and will be in the Player’s Handbook, but not everything in the Player’s Handbook will be linked to. All other materials that aren’t linked to are from other sourcebooks or aren’t allowed to be linked to per the 5th Edition Open Games License, so please refer to the appropriate sourcebooks for that information.

For the purposes of this guide, it will be assumed that you would not be multiclassing. While multiclassing can be excellent for many of these, this is for those who want to play the build all the way through in the same class. Guides that use multiclassing will be separate from these.

For spellcasters, you may notice substantial overlap between the spell lists of builds with the same base class. This is due to each guide utilizing a generically good spell list and not considering extenuating factors that will influence how you particularly sculpt your spell list. When creating your own spell list, you should take into account the campaign setting, what spells any other party members are capable of casting, potential overlap (ritual spells tend to overlap so it’s rare you need multiple people capable of casting them), or potential shortcomings in the parties total spell list. While this guide can definitely help point you in the right direction for crafting a spell list, you should use your judgement and preferences to figure out what spells make the most sense for your character.

To that end, please refer to the Spell List and Spell Tier list for any substitutions you’d want to make to the build.

The Complete Warlock Spell List

Warlock Spell Tier List – The Best Warlock Spells

One of the iconic Warlock subclasses, Fiend gets you some quite nice spells (especially the Fire spells like Fireball and Wall of Fire) on top of nice abilities to work with. While the flavor here is a bit more boring than other subclasses in my humble opinion, this is just a solid class all around that should operate well in any party that needs a blaster.

Dark One’s Blessing (Level 3) – B+ Tier – While you shouldn’t be getting hit often anyway, having a constant stream of temporary health makes you really hard to knock down.

1st Level Spells (Level 3) – D+ Tier – Burning Hands is atrocious, but Command can be good once you start getting higher spell levels.

2nd Level Spells (Level 3) – C+ Tier – Both spells are solid, even if Suggestion can’t be upcasted.

3rd Level Spells (Level 5) – A- Tier – Fireball is a huge pickup for Warlocks who normally don’t get good blast spells. This is easily one of the biggest reasons players pick Fiend!

Dark One’s Own Luck (Level 6) – B Tier – This is a pretty significant boost to your rolls and is even better than getting advantage on it as you both see the number first and, mathematically, you’ll get more from this than advantage.

4th Level Spells (Level 7) – A- Tier – Fire Shield isn’t ideal, but Wall of Fire is excellent and a spell Warlocks can’t normally get.

5th Level Spells (Level 9) – D- Tier – Yuck.

Fiendish Resilience (Level 10) – B Tier – Customizable damage resistance is really cool, and crucially, this is not limited to elemental damage types!

Hurl Through Hell (Level 14) – B Tier – While this is weaker than its previous version, it is still pretty good! If this works, this is some really nasty CC to use against a creature, just watch out for Legendary Resistances!

Species: Aasimar

The best species for your average build. Human is a consideration as well to grab Alert on top of Musician, but Aasimar just give a lot of value, and since you have a background you’re happy with, Aasimar is the next best choice.

Attributes

	POINT BUY
STRENGTH	8
DEXTERITY	15 (+1 background) = 16
CONSTITUTION	15
INTELLIGENCE	8
WISDOM	8
CHARISMA	15 (+2 background) = 17

Like many other casters, you want your spellcasting ability (Charisma in this case), Dexterity (as no medium armor proficiency), and Constitution all as buffed as possible. Charisma empowers your spells while Dexterity and Constitution help keep you alive.

---

Proficiencies: Deception and Intimidation

Being able to pick up Charisma based skills for Warlocks is definitely ideal to make you better in RPing scenarios.

---

Background: Entertainer

You need a background that gives you a bonus to Charisma at a minimum, but if you can get the best Origin feat to boot? This is an easy choice for Warlocks.

---

Starting Equipment – Leather Armor, Sickle, 2 Daggers, Arcane Focus, Book (occult lore), Scholar’s Pack, and 15 gp + 50 gp from background

Functionally the only choices you’d make with starting equipment beyond taking the optional starting gold instead, but considering the starting gold won’t get you nearly this much, I recommend just choosing the standard fare.

---

Class – Warlock

Picking Warlock gives you two abilities from the get go: Pact Magic and Eldritch invocations.

Pact Magic is the Warlock way of casting spells which differs greatly from how every other class does it. While all casters have a prepared spell list they can draw from, Warlocks lack spell slots and instead can only cast a few spells per short or long rest at their highest possible strength for your level. To that end, choosing spells that are both high impact and ideally can be upcast in order to get their full usefulness.

The second feature you get immediately is Eldritch Invocations, special powers you get as you go up in Warlock levels. There are definitely strong options at this point, but the best one right now is Pact of the Chain. Find Familiar is the best first level ritual spell in the game, and getting a substantially better version of it is obviously really potent. While you have a lot of options, the best choices for a familiar are easily the Imp, Quasit, or Sphinx of Wonder with their damage resistances, flight, and in combat capabilities.

---

Starting Spells

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Light (Aasimar)
Cantrip	Prestidigitation
1st Level Spell	Armor of Agathys
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Hex

For Warlocks, this is going to pretty much always be the starting spell list I would recommend.

For damage, you have to use Eldritch Blast. This is going to be your primary offensive spell not just now, but for your entire campaign as it gets better as you level up. You can’t do better than this (technically True Strike on your Light Crossbow is stronger until level 5, but since you want to take Agonizing Blast next level, you can’t afford to not have Eldritch Blast for it).

For your secondary cantrip choice, you can take any utility cantrip you like, I just believe that Prestidigitation is a bit better than the rest as its versatility is truly unmatched. If you prefer Mage Hand or Minor Illusion, then feel free to take those instead!

Of course, you have one more cantrip as you’re an Aasimar and it’s Light. While not the most needed for you as you have darkvision, it could be helpful to allies who don’t have it, or even as a distraction of sorts still making it a reasonable option to have.

For spells, you can simply take the best first level spells available to Warlocks with Armor of Agathys and Hex.

Armor of Agathys is an excellent defensive spell which will give you a bit of life to work with and punish enemies who attack you. Furthermore, it upcasts well which works perfectly with how Warlock spellcasting works.

Hex, on the other hand, is an offensive spell that lets you deal extra damage to the cursed target, and when that target goes down, you can move it onto someone else! This is really good to use in pretty much any fight that may be difficult as that damage can easily add up round after round.

On top of these spells, you also get the Find Familiar spell from your first Eldritch Invocation – Pact of the Chain. As mentioned one section ago, you get the option to pick from a lot of really excellent familiar choices like the Imp, Quasit, or Sphinx of Wonder making the already potent spell that much stronger.

Level 2

Class Features: Magical Cunning, Eldritch Invocations (Agonizing Blast, Pact of the Tome)

Spell Change Log: + Guidance (Tome) + Shape Water (Tome) + Comprehend Languages (Tome) + Detect Magic (Tome) + Witch Bolt

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Hex
1st Level Spell	Witch Bolt

Level two brings you Magical Cunning, two new Eldritch Invocations, and a litany of spells to work with.

Your first new ability is Magical Cunning, where once per day, you can conduct a short ritual to regain half you spell slots. This would normally be excellent, but with so few spell slots, this obviously won’t end up doing too much, but free spell slots are still free spell slots.

Your first Eldritch Invocation is arguably the most important one – Agonizing Blast. Adding your Charisma modifier to your cantrip damage is really important to have Eldritch Blast be effective, especially since you’ll be using it exclusively when you run out of spell slots in a fight.

The second Invocation is the main reason you get so many spells this level, Pact of the Tome. Pact of the Tome grants two cantrips and two first level ritual spells, and when you have so few ritual spells, you take as many as you can get. Since you already have an offensive cantrip, you should pick up the best utility ones you can get – Guidance and Shape Water. Guidance is an extremely potent cantrip, even with the small nerf given to it in the 2024 rules, and Shape Water has similar versatility to the very useful Prestidigitation making it a good option.

For your ritual spells, I like picking up Comprehend Languages and Detect Magic.

Not knowing what you’re reading or hearing can be a real pain, so nip that in the bud and take Comprehend Languages! Not every campaign will make use of other languages, but this will be extremely helpful in ones that do.

Detect Magic is simply an excellent ritual that can save you time and time again when you are about to walk into a trap, need to locate an object, need to surmise what’s causing a certain effect, and a thousand other applications.

Remember to coordinate with your party though, as if someone already has these ritual spells on their spell list, you don’t want to overlap. You can pick up other rituals that your party are missing instead so your team will be more well rounded.

With all that out of the way, your actual spell choice for this level is Witch Bolt. This is a nice damage spell ever since the 2024 rules update as you get some nice damage upfront, and even if you miss, you can trade your bonus action for additional damage on that missed target. This is a great option for those who need to bring down an enemy as quickly as possible.

Level 3

Subclass: Pact of the Fiend

Class Features: Dark One’s Blessing

Spell Change Log: + Burning Hands (Fiend) + Command (Fiend) + Invisibility + Scorching Ray (Fiend) + Suggestion (Fiend)

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Hex
1st Level Spell	Witch Bolt
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)

This level brings a lot to the table including your subclass, new subclass features, an expanded spell list, and second level spells.

You get to start off with Dark One’s Blessing which means whenever you or an ally close enough to you brings down an enemy, you get some temporary health as a reward. While it won’t be too much health in the beginning, the temporary health can absolutely stack up as you gain levels making you surprisingly hard to kill if you’ve had a long adventuring day. This ability is so potent that the DM will have to be careful with how much chaff to send at you as each enemy is a veritable health buffet for you.

You get an expanded spell as well with Burning Hands, Command, Scorching Ray, and Suggestion.

Burning Hands is a not so great damage spell that you probably won’t be using much if ever, but not the end of the world.

Command is a decent CC spell that isn’t great early as trading one of your precious spell slots and your action to only potentially rid an enemies of theirs isn’t great, but now that you can already target two enemies and eventually get up to five targets then this becomes much more appealing.

Scorching Ray is a decent blast spell that upscales decently, but it does get outclassed pretty quickly by Fireball when you get that in a few levels.

Your final expanded spell list spell is Suggestion. Finally, for your spell choice this level, you can pick up the excellent Suggestion. This spell is a powerhouse as it has excellent out of combat applications by forcing a course of action, but is similarly powerful in combat to make an enemy do something other than fight you! No matter what, you’re going to get mileage out of this spell.

For your spell choice, you can pick up Invisibility! Invisibility is king for infiltrations, escapes, surprises, and upcasts really well making it an extremely strong choice for any Warlock. Unlike Suggestion, this is going to be on your spell list for the long haul.

Level 4

Feat: Inspiring Leader (CHA)

Class Features: None

Spell Change Log: + Mage Hand + Mirror Image

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Hex
1st Level Spell	Witch Bolt
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)

Level four brings a cantrip, spell, and a feat!

Since you want to get that coveted 18 Charisma, you should take the excellent half feat – Inspiring Leader. Inspiring Leader gives you and your team a good amount of temporary health at the end of every short or long rest which is really powerful. If you already have an ally with this feat, you can opt for War Caster instead as the temporary health won’t stack. If you do keep this feat, don’t forget about using Musician as well!

Your cantrip choice really comes down to Mage Hand or Minor Illusion at this point, so you can pick the one you prefer. I like Mage Hand the tiniest bit more, but it’s completely personal preference.

For your spell choice, you can pick up Mirror Image! While this has no upcasting potential, being able to potentially avoid a few hits in the midst of a tough combat can be invaluable and keep you alive where other abilities wouldn’t.

---

Level 5

Class Features: Gaze of Two Minds, One with the Shadows

Spell Change Log: – Hex / + Counterspell + Fireball (Fiend) + Hypnotic Pattern + Stinking Cloud (Fiend)

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Witch Bolt
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)
3rd Level Spell	Counterspell
3rd Level Spell	Fireball (Fiend)
3rd Level Spell	Hypnotic Pattern
3rd Level Spell	Stinking Cloud (Fiend)

Level 5 means new Eldritch Invocations and new Pact spells!

Your first Eldritch Invocation choice is Gaze of Two Minds which is now extremely powerful with Pact of the Chain. Not only can you scout through your familiar (Imp and Quasit have natural invisibility), but you can even spellcast through your familiar. Imagine sending your invisible familiar into a room and having them cause mayhem with your spells without enemies being any the wiser!

Your second Eldritch Invocation choice with One with the Shadows. Being able to cast Invisibility when you’re in dim light or darkness for free is really strong and something you’ll be able to use really often.

Since there are so many strong third level spell options you want at this point, something needs to go to make room. Unfortunately, that means Hex has to hit the bench. At this point, you have better things to do than continue to cast Hex, even if it’s a bit better with the Eldritch Blast upgrade you just got.

This level brings two new Pact spells with Fireball and Stinking Cloud.

Fireball is famous for good reason. It’s hard to outclass the damage and AOE this spell brings at such at low level. Expect many of your spell slots to be dedicated to casting this.

Stinking Cloud, on the other hand, is solid CC that could potentially make multiple opponents waste their action if they fail the CON saving throw, something that may be easier said than done, but really effective against a lot of weaker targets (as is Fireball, but maybe you can’t afford to just blast away every time).

For your actual spell choices, you get to pick up the excellent Counterspell and Hypnotic Pattern.

The first spell you get access to is Counterspell, which is simply the best third level spell in the game. Using your reaction to rid an enemy of their action and trade spell slots is incredibly powerful and any ally who can learn Counterspell should.

For your second spell, this is a good time to pick up the excellent Hypnotic Pattern. This spell is such a potent CC spell that it’s in contention for best third level combat spell with Fireball as being able to potentially lock down multiple enemies with one spell slot is extremely powerful.

---

Level 6

Class Features: Dark One’s Own Luck

Spell Change Log: + Dispel Magic

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Witch Bolt
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)
3rd Level Spell	Counterspell
3rd Level Spell	Dispel Magic
3rd Level Spell	Fireball (Fiend)
3rd Level Spell	Hypnotic Pattern
3rd Level Spell	Stinking Cloud (Fiend)

Level 6 brings your next subclass ability with Dark One’s Own Luck.

This is like a juiced up Bardic Inspiration die that resets with each short or long rest which is quite nice. With an average addition of 5.5 on a roll, this is a pretty sizable roll increase when you need it.

For your spell choice, you can pick up Dispel Magic.

Dispel Magic is no Counterspell, but having access to both means you’ll never get caught flat footed by a spell.

---

Level 7

Class Features: Ascendant Step

Spell Change Log: – Witch Bolt / + Levitate (Ascendant Step) + Dimension Door + Fire Shield (Fiend) + Shadow of Moil + Wall of Fire (Fiend)

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Witch Bolt
2nd Level Spell	Levitate (Ascendant Step)
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)
3rd Level Spell	Counterspell
3rd Level Spell	Dispel Magic
3rd Level Spell	Fireball (Fiend)
3rd Level Spell	Hypnotic Pattern
3rd Level Spell	Stinking Cloud (Fiend)
4th Level Spell	Dimension Door
4th Level Spell	Fire Shield (Fiend)
4th Level Spell	Shadow of Moil
4th Level Spell	Wall of Fire (Fiend)

Level 7 brings fourth level spells, more Pact spells, and yet another Eldritch Invocation!

For your Eldritch invocation, I’m a big fan of Ascendant Step. Being able to Levitate for free, even at the cost of your concentration, is extremely good both for combat and exploration to reach areas that may have been tough to get to otherwise.

For your Pact spells, you get Fire Shield and Wall of Fire .

Fire Shield is decent if you need some elemental resistance, but with how few spell slots you get, it’s hard to justify using one on just reducing damage.

Wall of Fire, on the other hand, is a spell you absolutely want to be casting. With a good range, massive AOE, and great damage, this is an awesome damage and/or CC spell that’s awesome in functionally any combat.

Once again, it’s time to swap out a spell to make room for others and Witch Bolt has to hit the bin as the damage is just not going to keep up at these levels.

Your first spell choice is one of the best teleportation spells in the game with Dimension Door. Teleporting without line of sight is really powerful, and being able to take an ally with you makes this even better. If you need to infiltrate a building or make a quick escape, it’s difficult to do better than this.

Your second spell choice this level is the very excellent Shadow of Moil. Putting yourself in heavy obscurement is functionally the same thing as going invisible, plus you get the additional rider of the shadow attacking anyone who is close and manages to hit you for a bit of additional damage.

Level 8

Feat: Resilient (CON)

Spell Change Log: + Banishment

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Witch Bolt
2nd Level Spell	Levitate (Ascendant Step)
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)
3rd Level Spell	Counterspell
3rd Level Spell	Dispel Magic
3rd Level Spell	Fireball (Fiend)
3rd Level Spell	Hypnotic Pattern
3rd Level Spell	Stinking Cloud (Fiend)
4th Level Spell	Banishment
4th Level Spell	Dimension Door
4th Level Spell	Fire Shield (Fiend)
4th Level Spell	Shadow of Moil
4th Level Spell	Wall of Fire (Fiend)

Level 8 brings your second feat and this is a good time to pick up Resilient (CON). Getting more health on top of proficiency in constitution saving throws is really good for casters, especially if you don’t pick up War Caster.

For your spell choice, this is a good time to pick up Banishment. Banishment is a potent single target CC spell that can take enemies out of a combat for a full minute, and if they’re from a different plane, you have a chance to keep them there after the spell ends if they fail the save which is a really sweet way to not have to worry about them for the forseeable future!

---

Level 9

Class Features: Contact Patron, Visions of Distant Realms

Spell Change Log: + Arcane Eye (Visions of Distant Realms) + Contact Other Plane (Contact Patron) + Geas (Fiend) + Insect Plague (Fiend) + Storm of Radiance

SPELL LEVEL	SPELL NAME
Cantrip	Eldritch Blast
Cantrip	Guidance (Tome)
Cantrip	Light (Aasimar)
Cantrip	Mage Hand
Cantrip	Prestidigitation
Cantrip	Shape Water (Tome)
1st Level Spell	Armor of Agathys
1st Level Spell	Burning Hands (Fiend)
1st Level Spell	Command (Fiend)
1st Level Spell	Comprehend Languages (Tome)
1st Level Spell	Detect Magic (Tome)
1st Level Spell	Find Familiar (Chain)
1st Level Spell	Witch Bolt
2nd Level Spell	Levitate (Ascendant Step)
2nd Level Spell	Mirror Image
2nd Level Spell	Scorching Ray (Fiend)
2nd Level Spell	Suggestion (Fiend)
3rd Level Spell	Counterspell
3rd Level Spell	Dispel Magic
3rd Level Spell	Fireball (Fiend)
3rd Level Spell	Hypnotic Pattern
3rd Level Spell	Stinking Cloud (Fiend)
4th Level Spell	Arcane Eye (Visions of Distant Realms)
4th Level Spell	Banishment
4th Level Spell	Dimension Door
4th Level Spell	Fire Shield (Fiend)
4th Level Spell	Shadow of Moil
4th Level Spell	Wall of Fire (Fiend)
5th Level Spell	Contact Other Plane (Contact Patron)
5th Level Spell	Geas (Fiend)
5th Level Spell	Insect Plague (Fiend)
5th Level Spell	Storm of Radiance

Level 9 means yet another class ability, Eldritch Invocation, your final round of Pact spells, and the last spell level you’ll naturally get – 5th level spells.

Your class ability is Contact Patron which is simply the Contact Other Plane for free once per day which is nice and super flavorful that you actually have a way to talk to your patron now!

For your Eldritch Invocation, you can grab Visions of Distant Realms which is a really nice utility cantrip to have. While you do have a good scouting option with your familiar already, Arcane Eye is good for scoping out entire buildings, areas, or even dungeons so you know exactly what you’re getting yourself into. Information is power!

For your final Pact spells, unfortunately get some real unexciting options with Geas and Insect Plague. While you’ll liekly never be casting Insect Plague, Geas is a vrey strange command spell that you might get use out of if you need to employ a functional thrall in your service. It’s a really weird spell that’s hard to use, but maybe an amenable DM will be helpful in making this work.

For your spell choice, I recommend taking the best fifth level spells Warlocks naturally have access to – Storm of Radiance.

Storm of Radiance is a nice AOE damage and CC spell that can be really brutal if your allies can help you out a bit. While the damage itself isn’t super special, blinding and deafening anyone in the spell area is powerful against melee attackers, but ridiculous against any casters in the area. If your allies can help keep your enemies in that area, they will be substantially nerfed which will make that fight much easier.

You get your penultimate subclass feature here with Fiendish Resilience!

Getting resistance to a damage type of your choice can be really strong if you know that you’re going to be facing a lot of the same damage type. Otherwise, this is going to come up way less often than you may think, but is still a reasonable ability none the less.

Since you don’t get another known spell at this level, you have to settle with picking up another cantrip in Minor Illusion. This is the best cantrip Warlocks can learn that you don’t already have, so you may as well pick it up!

5th Level Spell	Insect Plague (Fiend)
5th Level Spell	Storm of Radiance
5th Level Spell	Teleportation Circle
6th Level Spell	Scatter (Mystic Arcanum)

Unlike other full casters where you get unfettered access to sixth level spells, you get Mystic Arcanum instead which used to be a lot more restrictive, but now is just a single prepared spell for each spell level that can be swapped out.

For your Mystic Arcanum, I like picking up Scatter. This spell is extremely versatile as you can use this to move allies and enemies alike around on the battlefield. Whether you need to make an escape, get allies to safety, or move enemies into hazardous areas, Scatter will get the job done.

For your spell choice this level, you get the best teleportation spells Warlocks can get – Teleportation Circle. While this does cost you 50gp per use and you need to use an established circle, this is a really effective way to travel without needing to hire a carraige or go on foot. Some DMs may be stingy with what areas have a circle to teleport to which can be a pain, but in the average campaign (and per the spell description), most major areas should have one making this an effective way of getting around.

5th Level Spell	Insect Plague (Fiend)
5th Level Spell	Storm of Radiance
5th Level Spell	Teleportation Circle
6th Level Spell	Scatter (Mystic Arcanum)

Your next feat is here, and while you could opt for more feats at this point, I think maxing out Charisma for the best possible spells makes the most sense at this point.

Level 12 brings an additional Eldritch Invocation as well, and you get the powerful Gift of the Protectors. Once per day, you can save an ally from going down which won’t always be that high impact, but could be fight winning in the right circumstances. Not having the choice of when it happens isn’t ideal, but the ability is strong enough that it’s hard to complain.

5th Level Spell	Storm of Radiance
5th Level Spell	Teleportation Circle
6th Level Spell	Scatter (Mystic Arcanum)
7th Level Spell	Crown of Stars (Mystic Arcanum)

Level 13 brings a new spell and your seventh level Mystic Arcanum.

For your Mystic Arcanum you should pick up the best seventh level spell available to Warlocks – Crown of Stars. This spell is easy to set up, only costs you a bonus action to use, and can even last through multiple combats if you’re lucky.

For your prepared spell, I like picking up Fly right now as, any time you cast this, will target three people which is a pretty effective use of your spell slot.

6th Level Spell	Scatter (Mystic Arcanum)
7th Level Spell	Crown of Stars (Mystic Arcanum)

While no new spells this level, you get your final subclass ability with Hurl Through Hell.

This is a powerful CC ability that, if the enemy fails the save, takes them out for a turn cycle on top of dealing a lot of damage. While this ability is weaker than its 5e iteration, you can use it again by expending a spell slot which can be nice if you know the enemy has a poor Charisma save.

5th Level Spell	Teleportation Circle
6th Level Spell	Scatter (Mystic Arcanum)
7th Level Spell	Crown of Stars (Mystic Arcanum)
8th Level Spell	Dominate Monster (Mystic Arcanum)

Your next Eldritch Invocation, your next Mystic Arcanum, and another prepared spell is here!

For Eldritch Invocation, this is a great time to pick up Lessons of the First Ones. While grabbing an origin feat now may seem crazy, Alarm is really good at every level so getting access to that is very nice.

For your Mystic Arcanum, there isn’t as obvious of a pick, but I still think there’s a clear winner with Dominate Monster. As I mention frequently, save or suck spells are a scary proposition, especially when you only have one shot per day, but if this hits, this is devastating. Taking control of a tough monsters will not only trivialize this combat, but potentially the next ones as well as long as the spell is holding. You do have to be mindful of Legendary Resistances at this point in the campaign, but as long as you do, this has a good chance of being a powerhouse.

For your spell choice, I like picking up Hold Monster. While “save or suck” spells can be really risky as using one of your few spell slots to get nothing is brutal, the upside is extremely high. If the target fails their saving throw, your martial allies can absolutely feast on them which will likely end them very quickly.

Since you already have maxed out Charisma, it’s time to bolster your Constitution more. Since this is your final feat, you may as well push up your Constitution with the +2 for better saving throws and a little more health.

7th Level Spell	Crown of Stars (Mystic Arcanum)
8th Level Spell	Dominate Monster (Mystic Arcanum)
9th Level Spell	True Polymorph (Mystic Arcanum)

Your final Mystic Arcanum and known spell are here!

For your penultimate spell choice, I ironically like back-stepping a lot to pick up Hold Person. This spell can be absolutely brutal to upcast, and in a lot of campaigns, you might be dealing with some real legendary humanoids at this point that this could be helpful against. If you’re not in that type of campaign, obviously feel free to swap this out for something else (although it is pretty slim pickings at this point).

For your Mystic Arcanum, you get the powerful True Polymorph. Being able to transform into any creature with a CR your level or lower is extremely powerful and can help you or an ally get back into a combat when they’re low on health or other resources that would normally invalidate them in that combat. Even at this level, you have quite the array of powerful options to pick from.

For your final Eldritch Invocation, you should definitely pick up Witch Sight. It’s hard to say how often Truesight will be relevant, but it’s such a nice insurance policy to have just in case you encounter convincing illusions or issues in the Ethereal Plane.

9th Level Spell	True Polymorph (Mystic Arcanum)

Level 19 brings your final prepared spell as well as your Epic Boon!

For your Epic Boon, I like the universally good Boon of Fate. Being able to potentially turn a failure into a success and vice versa, even if it’s once per short or long rest, can be the difference between surviving an encounter and not.

For your spell choice, you’re honestly running low on good options so the best of the rest seems to be Scrying. While definitely not the best scouting spell, it’s the only option you have if you’re looking to keep tabs on someone who is extremely far away from you.

For your capstone ability, you get Eldritch Master! The power of this ability is pretty up in the air as this only refreshes your expended spell slots rather than your Mystic Arcanum, and since those already come back on short rest, it’s campaign dependent on how good this is. Does your DM allow you to short rest as often as you want without repercussions? Then this is useless. Do they highly limit short rests? Then this can be very powerful. I wish a Warlock’s capstone ability was a bit more interesting/better, but you could do worse.
