For all D&D guides on Nat1gaming, they only use the main sourcebooks (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.
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.
Why Assassin Rogue?
While there is some amount of cool stuff you can do with the infiltration and disguise abilities, the main reason most players would choose this class is to deal an absolutely obscene amount of damage on the first round of combat. While it’s a shame that the only really good abilities are the first and last one, it is definitely fun to obliterate an enemy in one turn from the shadows.
Assassin Rogue Abilities Ranked
Assassinate (Level 3) – B+ Tier – Weaker than it used to be, but this feature is still quite good as advantage on initiative and the ability to Sneak Attack most targets round one is nice.
Assassin’s Tools (Level 3) – C+ Tier – I’ll never say no to two proficiencies, and both can be good if you’re creative with them.
Infiltration Expertise (Level 9) – C+ Tier – The first half of this ability is pure utility, and can be useful in the right situations. Roving Aim is definitely useful as well, but I question how often you want to be attacking from range which does limit the usefulness of this ability. Overall, I’d say this ability is solid but that will definitely vary from player to player.
Envenom Weapons (Level 13) – D+ Tier – The Poison cunning strike is not the option I would want to use most of the time, and the additional damage granted by this ability isn’t much of an incentive. This isn’t bad if you’re facing an enemy with low Constitution, but this is very unexciting.
Death Strike (Level 17) – B Tier – Constitution saving throws are rough as a lot of enemies have really high Constitution scores, but if they fail against this, they can get obliterated which is always fun.

Level One Build
Species: Halfling
Attributes:
| POINT BUY | |
| STRENGTH | 8 |
| DEXTERITY | 15 (+2 background) = 17 |
| CONSTITUTION | 15 (+1 background) = 16 |
| INTELLIGENCE | 8 |
| WISDOM | 14 |
| CHARISMA | 10 |
Class: Rogue
Class Features: Expertise, Sneak Attack, Thieves’ Cant, Weapon Mastery
Skill Proficiencies: Acrobatics, Insight, Investigation, and Perception
Background: Criminal (Alert)
Starting Equipment: Scimitar, Dagger, Shortbow and quiver of 20 arrows, Leather Armor, Thieves’ Tools, and 11 gp + 50 gp from background
Species: Halfling
While I’m not a big fan of what Halfling brings to the table, being able to Hide behind a larger party member is really good if you miss with your Vex weapon and don’t have any other form of obscurement in combat. That said, the other abilities are decent as well, even if they won’t be relevant that often.
Attributes
| POINT BUY | |
| STRENGTH | 8 |
| DEXTERITY | 15 (+2 background) = 17 |
| CONSTITUTION | 15 (+1 background) = 16 |
| INTELLIGENCE | 8 |
| WISDOM | 14 |
| CHARISMA | 10 |
Dexterity and Constitution are always going to be the Rogue’s primary stats, and your extra points can go to either pumping Wisdom or Charisma depending if you want better saving throws or better conversation skills.
Proficiencies: Acrobatics, Insight, Investigation, and Perception
Common proficiencies for Rogue as between these and your background you have all the DEX skills covered as well as other great proficiencies.
Background: Criminal
Good proficiencies, great feat, and it makes a lot of sense with Rogue in general
Starting Equipment – Scimitar, Dagger, Shortbow and quiver of 20 arrows, Leather Armor, Thieves’ Tools, and 11 gp + 50 gp from background
This is very similar to the starting equipment, but the Scimitar is much better than the Shortsword so you have to take the starting gold to get it.
Class – Rogue
Rogues are a very versatile class with a lot of practical applications in and out of combat making them a fan favorite. Starting off, Rogues come with three abilities: Expertise, Sneak Attack, Thieves’ Cant, and Weapon Mastery.
Expertise allows you to take two of your skills and add double your proficiency bonus to them to make them extremely reliable. While the skills you select really depends on what you personally prioritize, it’s hard to go wrong with Perception and Stealth. These are two excellent skills you are going to constantly use so making them as consistent as possible will constantly pay off.
The second ability is the Rogue’s most iconic one – Sneak Attack. Sneak Attack adds extra damage if you can attack an enemy while you have advantage from any means whether that’s through having allies near, attacking from hiding, or any other means of gaining advantage you may naturally have.
The third ability, which is really just pure flavor, is Thieves’ Cant. This is like its own language that only other rogues or similarly nefarious individuals would know so you can speak in code and such.
The final ability is Weapon Mastery, and you should take the Scimitar and Shortbow mastery considering that’s what you’re going to be using! As a note, make sure your Scimitar is in your main hand to make use of its Weapon Mastery property effectively.
The Build Level 2 Onward
Level 2-5
Level 2
Class Features: Cunning Action
One of the best abilities on Rogue, you can now convert your Bonus Action into a Dash, Disengage, or the Hide action. While the Hide Action is going to be the most common action taken so you can continuously get Sneak Attacks, Dash and Disengage are also excellent actions to take if you really need to get out of wherever situation you’re in.
Level 3
Class: Assassin
Class Features: Assassinate, Assassin’s Tools, Steady Aim, Sneak Attack to 2d6
Level 3 brings your subclass, Assassin, and you get three new abilities this level with Assassinate, Assassin’s Tools, and Steady Aim!
Your first ability is likely the whole reason you took this subclass, Assassinate! You get advantage on Initiative rolls which is excellent (especially with Alarm as your origin feat), you have advantage against any target that hasn’t taken a turn yet, and your Sneak Attack damage gets a bonus equal to your Rogue level. While this is a bit weaker than it used to be, this ability is still good enough to be a draw to this class.
Assassin’s Tools gives you proficiency for both the disguise kit and the poisoners kit. How good this ability is really depends on how much work the player wants to put in utilizing these, but these can be decent if they’re willing to work with them.
Finally, you get Steady Aim which lets you give up your bonus action and movement for a turn in order to have advantage on your next attack. If you have no way to gain advantage otherwise, this is a really nice way to get it!
Level 4
Feat: Skulker (DEX)
Class Features: None
Level 4 brings your first feat, and Skulker is perfect for Rogues! Getting some amount of Blindsight is nice, but the real prizes here are the advantage to hide in battle and missing with an attack doesn’t reveal you which gives you another chance to get that Sneak Attack! These are some really nice abilities that you’re going to get a lot of mileage out of.
Level 5
Class Features: Cunning Strike, Uncanny Dodge, Sneak Attack to 3d6
Level 5 brings two new features to the table with Cunning Strike and Uncanny Dodge.
Cunning Strike is an interesting ability that lets you trade in Sneak Attack damage dice for a small, but generally good additional effect. You start with three different options for your Cunning Strike – Poison, Trip, or Withdraw.
Poison can be solid, but Constitution saving throws are generally the easiest to save out of.
Trip is definitely solid if you have other martial allies and especially if they’re behind you in the turn order (which they will likely be).
Withdraw lets you reposition without drawing opportunity attacks so you don’t have to use your Cunning Action to disengage.
Overall, this ability is pretty good as you have versatile options that can all be impactful!
Uncanny Dodge lets you use your reaction to halve the damage of one incoming attack. Unfortunately, this is a pretty bad ability as multiattacks are going to become more common making the ability to halve just one of those attacks pretty forgettable. Furthermore, Defensive Duelist is going to be taking your reaction more often than not, but if you know that you have to take some damage on a turn, then this is here for you.
Level 6-10
Level 6
Class Feature: Expertise
You get two more bouts of Expertise to pass around, and once again, it really depends on whatever skills you find yourself using often. In a generic sense, I like picking up Insight and either Investigation (if no INT people in your party) or Sleight of Hand.
Level 7
Class Features: Evasion, Reliable Talent, Sneak Attack to 4d6
Level 7 brings two neat abilities with Evasion and Reliable Talent.
Evasion is a really solid ability that makes any effects that forces Dexterity based saving throws way worse against you as you naturally mitigate half of their effect and potentially the whole effect if you pass the save.
Reliable Talent is a cool ability that makes all rolls for skills you’re proficient in be a minimum of a 10, which means you have a much higher chance of passing skill checks with skills you are proficient in and you’ll very rarely fail checks involving skills you have Expertise in.
Level 8
Feat: Crossbow Expert (DEX)
Class Features: None
Level 8 brings another feat, and while you could go straight to 20 Dexterity for the highest AC, attack rolls, and initiative, I like taking two feats instead. To that end, and I really like grabbing Crossbow Expert.
While I do always enjoy Rogues who are in melee, their low AC makes that game plan a bit of a liability, especially if you don’t have many allies with you on the front lines. It’s much safer for you to hang back with two Hand Crossbows and attack from afar, especially if you only hit on your second attack as that’ll break you out of hiding, and if you were in melee range, the enemy could just wallop you freely. If you want to be a Rogue that stays in melee, you can snag Defensive Duelist (DEX) here instead.
Level 9
Class Features: Infiltration Expertise, Sneak Attack to 5d6
Level 9 brings your next subclass ability with Infiltration Expertise!
This ability has two parts where one is flavorful and the other is pragmatic. The flavor ability is you can create a whole false identity for yourself which is super cool, but the practical applications are extremely lacking. While a neat ability for a single player game, DND is played in groups and having one player go off on their own to do their own thing is generally rare and frowned upon. While a neat ability, it isn’t one you’ll likely use often. The more pragmatic part of this ability is Steady Aim no longer reduces your speed to 0. Definitely solid if you find yourself using your bow a lot!
Level 10
Feat: Dual Wielder (DEX)
Class Features: None
You get yet another feat this level, and you can finally get 20 DEX with Dual Wielder. Now you can take your extra attack with the Hand Crossbow as part of your main attack which is super helpful if you happen to miss your first attack, and with Skulker, you can remain hidden if you miss all of your attacks. These three feats are more or less the core of the new Rogue in my opinion.
Level 11-15
Level 11
Class Features: Improved Cunning Strike, Sneak Attack to 6d6
Level 11 brings an improvement to your Cunning Strike! Now you can use two Cunning Strike features simultaneously, and while you still have to pay the associated costs, this is still a pretty solid ability!
Level 12
Feat: Constitution to 18
Class Features: None
More health and better saving throws is never a bad thing, even if you’re probably not getting hit that often!
Level 13
Class Features: Envenom Weapons, Sneak Attack to 7d6
Your next subclass feature is Envenom Weapons!
This incentives you to use the Poison option of your Cunning Strike as, whenever the enemy fails their save, they take 2d6 Poison damage that ignores resistance! While this isn’t a lot of damage, the enemy has to make the saving throw every turn which means, if they keep failing, they keep taking the damage. Realistically, this isn’t that impactful either way, but it is a nice ability for players who have been happy with the Poison option thus far.
Level 14
Class Features: Devious Strikes
You get your final upgrades to your Cunning Strikes with Devious Strikes!
Like the original Cunning Strikes, you get three more options that have both higher costs and more powerful effects with Daze, Knock Out, and Obscure.
Daze can limit somewhat limit what an enemy does on their turn, but considering not many monsters have uses for their Bonus Action, this probably isn’t that good of a feature.
Knockout takes out most of your Sneak Attack dice, but you have a chance to render an enemy unconscious until it passes the save or takes damage. This ability could have been strong if they were stunned for a full turn cycle, but just one ally being able to take advantage of this makes this pretty bad.
Obscure is easily the best of these options as you can potentially blind an enemy which is a pretty brutal status condition.
Overall, this ability is not particularly great, but they can’t all be winners.
Level 15
Class Features: Slippery Mind, Sneak Attack to 8d6
Gaining proficiency in Wisdom and Charisma saving throws is very strong, even if it comes a bit late in your progression. Wisdom, in particular, is the most common spell saving throw you’ll have to contend with so you’ll have a substantially better chance of passing these saves now.
Level 16-20
Level 16
Feat: Constitution to 20
Class Features: None
Max health and CON saves is always great!
Level 17
Class Features: Death Strike, Sneak Attack to 9d6
Your capstone ability for Assassin is Death Strike!
This is an upgrade to Assassinate as your target now has to pass a relatively high DC Constitution saving throw or take double damage. Mind you, you are already hitting for extra damage if you connect with an enemy the first round of combat, so you can deal some really incredible damage here. In just one attack, you can very easily deal over 100 damage! Realistically, this isn’t going to be that different from what the average Fighter can put out at this level, but seeing those damage dice fly is always fun.
Level 18
Class Features: Elusive
As long as you aren’t unconscious, enemies can’t have attacks at advantage against you anymore. This can be good, but it’s not too often that enemies are going to have advantage on attacks against you anyway, so this likely isn’t going to come up often.
Level 19
Epic Boon: Boon of Combat Prowess
Class Features: Sneak Attack to 10d6
Your Epic Boon choice, as I will pick for every martial character, is the Boon of Combat Prowess. Converting a miss into a hit is functionally getting an Extra Attack, but better, and I will take an additional attack every day of the week.
Level 20
Class Feature: Stroke of Luck
Every short or long rest, you can turn any failed d20 test into a critical success. Obviously this is pretty strong, even if you don’t get to use it often.
