Smiter

When you hit a creature with a melee weapon Attack, you can deal extra radiant or force damage (your choice) to the target, in addition to the weapon's damage. If you already have a Smite feature such as the Paladin's Divine Smite or the Warlock's Eldritch Smite, the extra damage equals the damage from that feature; otherwise, the extra damage is 2d6.

Once you use this feature, you must finish a short or long rest before you can use it again.
