Blightstorm

A roiling black stormcloud laced with green lightning and spore-laden winds appears, filling the air with withering rot, venomous pollen, and the death-rattle of corrupted nature. All creatures in the area must succeed on a Hard END save or take 32 Poison damage and gain the Sickened condition for 4 phases. On a successful save, they take half damage and are Sickened for 1 phase. Creatures of the Plant type must increase the difficulty of the save by category. The area becomes blighted for the duration, rendering natural healing and plant growth impossible during that time.
