Choose up to six creatures you can see within range. Each target must make a Constitution saving throw. On a failure, a target begins farting uncontrollably, creating a 5-foot-radius sphere centered on itself filled with a pungent green gas that moves with it for the spell's duration. Additionally, the target becomes poisoned and can only take an action, a bonus action, or move on its turn. On a successful save, a target becomes sluggish, and can only move half its speed until the end of its next turn. 

An affected target must repeat its Constitution saving throw at the end of each of its turns, taking 2d8 poison damage on a failure and ending the spell's effect for it on a success. 

All creatures within the fart gas have disadvantage on Charisma ability checks and on Wisdom (Perception) checks that rely on smell. Any creature that breathes the gas is poisoned until it leaves the space containing the gas. 

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the poison damage increases by 1d8 for each slot above 6th.
