Elemental damage from the hexblade's curse seems to apply to claw attacks in werewolf form if a cursed weapon is equipped prior to transforming.

Not sure if this is a bug or intentional, figured it was worth mentioning.

Edit: Removing the weapon still causes the elemental damage, for some reason.

Hexblade Curse damage is direct onCharacter applied damage, which is why you're still getting it. You would still get it if you cast it, and then punched something with your fists, as well.
