Weapon

Legendary Requires Attunement

You gain a +2 bonus to attack and damage rolls made with this magic weapon.   Once per turn with this weapon, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. You don't need advantage on the attack roll if another enemy of the target is within 5 ft of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.   If a melee attack made by this weapon is a critical hit, or kills or knocks the target unconscious, you gain the effects of the invisibility spell for 1 minute. The effect does not require concentration, but ends after the duration, if an attack is made, or spell is cast by you.

An evil looking dagger, intricately carved with what seems like wells and channels flowing up its sides.
