[RPG] way to make the Elven Accuracy feat work with the second benefit of Great Weapon Master


Is there a way to make the Elven Accuracy feat work with the second benefit of Great Weapon Master?

Elven Accuracy (XGtE, p. 74) says:

Whenever you have advantage on an attack roll using Dexterity, Intelligence, Wisdom, or Charisma, you can reroll one of the dice once.

The second benefit of Great Weapon Master (PHB, p. 167) says:

Before you make a melee attack with a heavy weapon that you are proficient with, you can choose to take a – 5 penalty to the attack roll. If the attack hits, you add +10 to the attack’s damage

Boundary Conditions

Any official material (non-UA) is fine, as are optional rules like feats (obviously) and multiclassing.

What does not work

The Shillelagh cantrip lets you attack using Wisdom, but the Quarterstaff is not heavy.


Champion Fighters could really benefit from an increased crit chance, and melee advantage is very easy to get.

Best Answer

The most optimal way to do this would be to play a Half-elf Hexblade.

Drow (PHB) & Shadar-Kai (UA Elf Subraces) come in second (+1 to Cha vs Half-Elf's +2), and other elves are still viable (just a little behind on Cha). You can start using a heavy weapon once you reach 3rd level in Warlock with the Hexblade Patron.

Hex Warrior (XGtE 55,56)

  • Proficiency with martial weapons (as well as medium armor and shields)
  • Select a single weapon which is not two-handed and use Charisma for attack and damage. This extends to your pact blade, regardless of its type.

Pact of the Blade (PHB 107)

  • At 3rd level you can choose to summon any melee weapon as your Pact Blade. At this point you may choose your heavy weapon and attack with Charisma.

Also note that your attack cantrips such as Eldritch Blast and Shocking Grasp would benefit from the reroll as well.

Here are some ideas that come close but I don't think quite work:

  • 3rd level Paladin with the Oath of Devotion
    • Sure, you add Charisma to your attack. That probably doesn't count as using Charisma. Let's call it a bonus. Note that you don't add Charisma to your damage. (Maybe you can convince your DM that this works. It comes down to what using Charisma actually means in the context of the various rules.)
    • Also, this takes an action where you could have been attacking and uses up your Channel Divinity that you only get once per rest.
  • Kensei Monk with a Bow
    • Improvised weapons don't inherit properties from what they really are. Using a bow as a club/staff doesn't give it the heavy property and doesn't make it a monk weapon. In melee, a bow is just a length of wood (not even as good as a staff). (It certainly doesn't inherit the ranged property.)

Honestly, it makes sense that you are having a hard time using a heavy weapon without using Strength. This is part of the game balance that 5e sets up. If anything Hexblade/PoB breaks this balance by using Charisma with any weapon. Don't be surprised if you see Hexblade as the go-to for getting around balancing rules.
