Hammer of Thunderbolts

Weapon (Maul or Warhammer), Legendary (Requires Attunement)

• Bonus: You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon.
• Thunderous Throw: The weapon has 5 charges. You can expend 1 charge to make a ranged attack with the weapon, hurling it as if it had the Thrown property with a normal range of 20 feet and a long range of 60 feet. If the attack hits, the weapon unleashes a thunderclap audible out to 300 feet. The target and every creature within 30 feet of it other than you must succeed on a DC 17 Constitution saving throw or become Stunned until the end of your next turn. Immediately after hitting or missing, the weapon flies back to your hand.
• Regaining Charges: The weapon regains 1d4 + 1 expended charges daily at dawn.

• Giants’ Bane: When you roll a 20 on the d20 for an attack roll made with this weapon against a Giant, the creature must succeed on a DC 17 Constitution saving throw or die.
• Might of Giants: The Strength score bestowed by your Belt of Giant Strength or Gauntlets of Ogre Power increases by 4, to a maximum of 30.
