Death Blossom

A swarm of petals swirl around the caster in a 30-foot-radius sphere. Each creature in that area must make a Constitution saving throw. On a failed save, a target takes 3d6 necrotic damage and becomes blinded until their next turn. The target takes only half the damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
