Weapon (handaxe), rare
When you roll a 20 on your attack roll with this magic weapon, the target takes an extra 7 damage of the weapon’s type.
Proficiency with a handaxe allows you to add your proficiency bonus to the attack roll for any attack you make with it.
Notes: Damage: Additional, Damage, Combat, Light, Thrown
This is not the correct bonus for a Vicious weapon. It should be an additional 7 damage, not an additional 2d6 damage.
Edit: Fixed!
