Bitterblossom

A horde of deadly butterflies swarm around you to a distance of 5 feet for the duration, protecting you from attacks and harassing foes. Until the spell ends, you have the following benefits:

Fluttering Cloud. You have half cover.

Feasting Swarm. Whenever a hostile creature enters the area for the first time on a turn or starts their turn there, it must make a Dexterity saving throw. On a failed save, the creature takes 2d6 piercing damage and is blinded until the start of your next turn, or until that creature leaves the area of the spell. On a successful save, the creature takes half as much damage and is not blinded.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
