Darkhunter's Spear (5e Equipment)

Weapon (spear), very rare (requires attunement)

This spear is made of a single bone from an ancient beast and tipped with a blade of volcanic glass. You gain a +1 bonus to attack and damage rolls made with this magic weapon, which deals an extra 3d6 piercing damage against creatures of the aberration type. Once per turn, when you hit a regenerating creature with an attack using this magic spear, you can attempt to disable its ability to regenerate. When you do so, the creature must succeed on a DC 17 Constitution saving throw, or its regeneration doesn't function at the start of its next turn.
