Corpse Bloom

You gesture at the corpse of a small, medium or large creature within range and cause it to bloom into a font of death and decay. The ground within 5 feet of the target corpse becomes difficult terrain. The effect spreads to any other eligible corpse within or partly within this area of difficult terrain.

Any creature that starts its turn within this area of difficult terrain or moves into it for the first time on a turn must succeed on a Constitution saving throw or take 1d4 necrotic damage and become Poisoned. The corpse of a small, medium or large creature which dies while Poisoned in this manner will bloom into a new source of corruption.

When the spell ends, any affected corpses become inert and any Poisoned conditions inflicted by the spell end.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 and the duration of the spell doubles for each slot level above 2nd.
