Radiant Soul

Level 6 Celestial Warlock

Starting at 6th level, your link to the celestial allows you to serve as a conduit for radiant energy. You have resistance to radiant damage AND whenever you deal damage in a round, you may use your bonus action on your turn to add your prof modifier of d4 temporary hit points to a friendly creature.   Also because I don't want to make another statblock, your healing dice increase to a d6.
