You reach out towards a point you can see within range, creating a 20-foot radius sphere filled with festering, necrotic energy that withers and decays everything within it. When a creature enters the blighted area for the first time on a turn or starts its turn there, it must make a Constitution saving throw. On a failed save, the creature takes 4d8 necrotic damage. In addition, until the beginning of its next turn, the creature subtracts 1d4 from all of its attack rolls and saving throws, as if under the effect of the bane spell. On a successful save, the creature takes half as much damage, and suffers no additional effects.

Undead creatures in the spell's area take no damage, and are bolstered by its necrotic power. While standing in the spell's area, undead creatures add 1d4 to their attack rolls and saving throws, as if under the effect of the spell bless.

At Higher Levels : When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
