Divine Punish

Target one creature that you can see within range that has temporary hit points, or is under the effect of Aid or other maximum hit points increasing effects. The creature must make a Constitution saving throw, on a failed save its temporary hit points and maximum hit point increase are destroyed and it receives radiant damage equal to the temporary hit points and maximum hit point increase. Its maximum hit points are then reduced by that equal amount to a minimum of 1 until it finishes a long rest or until is subjected to a Greater Restoration spell. It also cannot gain temporary hit points until the end of your next turn.

When you cast this spell using a spell slot of 6th level or higher, you can target one additional creature for each slot level above 5th.
