Channel Damnation

As an action, you point your finger at a creature you can see within 120 feet of you and speak a powerful, damning curse. That creature and all creatures within 10 feet of it must make a Charisma saving throw. On a failed save, a creature takes fire damage equal to 1d12 + your cleric or paladin level and is bound by searing, hellish chains. On a successful save, a creature takes half as much fire damage and isn’t bound by the chains. A bound creature’s speed is halved, and it takes 1d12 fire damage at the start of each of its turns for up to 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
