2nd-level conjuration

Casting Time: 1 action

Range: 30 feet

Components: S, M (a mushroom cap)

An array of wispy luminous mushrooms sprouts from a creature you can see within range. The target must succeed on a Constitution saving throw or 1d8 mushrooms grow out of its body. While the target has at least one mushroom growing from it, the target is poisoned. The target or a creature within reach of it can use its action to remove a mushroom. Removing a mushroom deals 1d4 poison damage to the target.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the poison damage dealt to the target when a mushroom is removed increases by 1d4 for every slot level above 2nd.
