Bat Bogey Hex

You transform the bogeys of a creature you can see within range into attacking bats. The target must succeed on a Strength saving throw or take 1d4 slashing 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 5th level (2d4), 11th level (3d4), and 17th level (4d4).
