Belching Sporecap

As a bonus action, you summon a spherical sporophyte on legs of hyphae. The sporophyte is surrounded by a 10 ft radius cloud of stinking spores. Creatures that enter the cloud for the first time on a turn or start their turn there must succeed on a Constitution saving throw against your spell save DC or take 2d6 necrotic damage and have disadvantage on attack rolls until the end of their next turn. On a successful save, the creature takes half damage and does not have disadvantage. As a bonus action while the sporophyte is active, you may move it up to 30 ft in any direction.

Higher Level Spells. When you cast the spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every level above 2nd.
