Chimes of the Heavens

When this spell is cast, you create a cacophony of melodious sounds which can be heard up to 100' away. All undead creatures within 30’ of you immediately take 4d6 damage plus your spell casting modifier unless they succeed on a Constitution saving throw, in which case they only take half damage. This damage counts as both thunder and radiant damage. In addition, undead creatures cannot willingly enter the area of effect, and any that are currently within it are pushed just outside the area of effect, triggering any opportunity attacks.

In addition, all living creatures within the spell's area of effect, and/or those entering it for the first time, regain hit points equal to 4d6 plus your spell casting modifier.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the healing and damage inflicted increases by 1d6 for each slot level above 5th.
