Blessing of the Redeemer

You bless a creature with the spirit of redemption, creating an aura of justice around the target that empowers them in the face of adversity. The next 5d10 damage that is taken by the target will instead heal it. If the target is healed for the full damage before concentration ends, they are overcome with the spirit and will be prevented from attacking the target that last damaged them for 1 turn.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d10 for each slot level above 4rd
