Armor of Fungi

A vast array of fungi sprouts from and covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the fungi sprays them with poisonous gas, and the creature takes 5 poison damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both the temporary hit points and the poison damage increase by 5 for each slot.
