Celestial Bulwark

Your devotion has been tested and you've learned to draw on higher powers to distract your enemies and protect your allies. You may now activate your Radiant Soul ability as a bonus action a number of times equal to your proficiency bonus. Additionally, while Radiant Soul is active, the first creature you hit with an attack or spell on your turn becomes distracted by your celestial luminescence, which hinders the creature's attacks. Until the start of your next turn, that target has disadvantage on any attack roll that isn’t against you. You regain all uses of Radiant Soul on a Long Rest.
