Cadaverous Bloom

You cause noxious mushrooms to erupt from a nearby corpse. A target small or medium creature's corpse erupts with fungi that emit toxic spores in a 10 foot radius around the corpse.

When a creature enters the spell's area for the first time on a turn or starts its turn there, it begins choking on spores and must make a Constitution saving throw. On a failed save it gains the poisoned condition until the end of its turn and takes 2d8 poison damage, or half as much on a successful one. This spell ends instantly if the corpse takes 15 or more fire or acid damage in a single turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage dealt increases by 1d8 and the maximum sized targetable corpse increases by 1 size category for each slot level above 2nd.
