You tear apart the necromantic energies of an undead creature. Make a ranged spell attack. On a hit, the target takes 10d8 radiant damage. If the target has 25 hit points or fewer after taking this damage, it must succeed on a Wisdom saving throw or be destroyed. On a successful saving throw, the creature becomes frightened of you until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, you deal an additional 1d8 radiant damage per each slot level above 6th.
