Expeditious Excrete

This spell allows you to give enemies diarrhea at an incredible pace. When you cast this spell, make a melee spell attack to apply the effect. On a hit, the target takes 1d8 poison damage and falls prone. A hit creature must succeed in a Constitution saving throw at the start of its next turn or take an additional 1d8 poison damage.

Until the end of the target's next turn, any creature that enters 5 feet of the target must succeed in a Constitution saving throw or be repelled 5 feet away.
