The Midnight Servants Sacred Seal

When casted, a seal appears on your forhead and a silver glowing moon appears above your head giving off dim light for 10 ft. Until the spell ends, you can use a bonus action to move the moon above a target you can see within range. When the target is hit by an attack which deals damage you may roll 1d10 and add your wisdom modifier. Deal this much radiant damage to the target, or heal the attacker by this much. Once someones attack procs this effect, they cannot do so again until the beginning of their next turn.

At Higher Levels. When you cast this spell using an 7th level spell slot, the duration of the spell becomes 8 hours.

When cast at 8th level you roll 2d10 instead of just 1d10.
