Cleansing Wave

You unleash a wave of purifying energy in a 30-foot line that sweeps away blighted energies. Each creature in that line regains 2d6 hit points and is cured of one blighted effect for 1m. If a creature is a Blighted One, they must make a constitution saving throw (DC 14). On a failure, they take 3d6 radiant damage instead.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the healing increases by 1d6 for each slot level above 2nd, but you must sacrifice an additional 4 HP per level.
