Yeast Infection

You cause a thick cloud of active yeast to appear momentarily on top of one creature you can see within range. The target must succeed on a Constitution saving throw, or it takes 1d6 poison damage and is poisoned. At the end of each turn, the creature my attempt another Constitution saving throw. If successful, they are no longer poisoned. 

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
