Divine Bulwark

You touch one willing creature that you can see and grant a divine blessing that shrouds both yourself and the creature for one hour or until you use your action to dispel it.

For the next hour, whenever you or the creature you've blessed is hit by an attack or fails a saving throw while you can see them, you can use your reaction to grant them a bonus to either their AC or Saving Throw equal to your spellcasting modifier.
