Vomit Rebuke

You open your mouth, and the creature that damaged you is covered in a viscous vomit. The creature must make a Dexterity saving throw. It takes 2d10 poison damage on a failed save and is poisoned, or half as much damage on a successful one and is not poisoned. A poisoned creature can repeat the saving throw to shake off the poison condition at the end of each of its turns.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d10 for each slot level above 1st.
