Create Mushroom Bed

Black smoke shoots out and touches somewhere on the ground you can see and turns the ground into a mushroom bed. Until the spell ends, the magic mushroom bed fills a 10-foot cube. Any creature in the mushroom beds space must succeed on a Dexterity saving throw or take 1d8 necrotic damage. A creature must also make the saving throw when it moves into the mushroom's beds space for the first time on a turn or ends its turn there.

The mushroom bed consumes any objects and turns them into mushrooms in its area that isn’t being worn or carried.

The spell’s damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
