Cause Gas

You attempt to plague a creature you can see within range with terrible gas. It must make a Constitution saving throw. If it fails the saving throw, it is overcome with terrible gastrointestinal pain and begins to fart uncontrollably. The creature's movement speed is halved and it makes all ability checks with disadvantage until the spell ends.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 1st. The creatures must be within 30 feet of each other when you target them.
