Arf's Violent Vomitball

A strange spell, invented and made famous as the signature spell of the Gnoll Sorcerer, Arf Sunpelt.

You stick your finger down your throat, causing yourself to retch and shoot a blast of projectile vomit that is charged with your internal magic, rocketing it to a point within range. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 7d6 acid damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
