Acid Reflex

You unleash an old Witch conjuration targeting a living creature you can see within range, multiplying the amount of acids in the creatures stomach.

The target must succeed on a Constitution saving throw, on a failed save at the start of the creatures turn, it vomits stomach fluids taking 1d4 acid damage and have disadvantage on the next attack roll it makes before the end of its next turn.

This spell's damage increases by 1d4 when you reach 3th level (2d4), 7th level (3d4), and 11th level (4d4).
