You create a 20-foot-radius sphere of poisonous, yellow-green fog centered on a point you choose within range. The fog spreads around corners and its area is heavily obscured. When a creature enters the spell's area for the first time on a turn or starts its turn there, it must make a Constitution saving throw, taking 5d8 poison damage on a failure or half on a success.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
