Slaying

Weapon Enchantment, Very Rare (requires attunement)

When creating a slaying weapon you determine what creature type it’s designed to slay, or roll randomly on the creature type table. Slaying enchantments are different depending on if they’re for ammunition or a weapon.

Ammunition. If a creature of the chosen damage type takes damage from the ammunition, the creature makes a DC 17 Constitution saving throw, taking an extra 6d10 force damage on a failed save or half as much extra damage on a successful one. After dealing its extra damage to a creature, the ammunition becomes nonmagical.

Weapon. If a creature of the chosen damage type takes damage from the weapon, the creature takes an extra 3d10 force damage.
