Blinding Ash

A puff of smoldering ash bursts toward one creature you can see within range. The target must succeed on a Dexterity saving throw or take 1d4 fire damage and suffer disadvantage on the next attack roll it makes before the end of its next turn.

At Higher Levels. The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
