CF: Divine Strikes
Cleric | Paladin | Radiant | Smite
You gain the ability to infuse your attacks with divine energy. Once per turn, when you successfully hit a creature with an attack, you can cause the attack to deal an extra 1d8 Radiant (or another damage type, if have a feature that allows it) + extra d8s equal to your Half-Proficiency. You do this as a free action / ◇.
This Feature can also be used with, and can trigger, Smites, though it can still only be done once per turn.
