This spell creates a cloud of glittering golden particles within the area of effect. Those in the area must roll a successful dexterity saving throw or be blinded (a blinded creature can't see and automatically fails any ability check that requires sight/attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage) for 1d4 + 1 rounds. In addition, all within the area are covered by the dust, which cannot be removed and continues to sparkle until it fades. Note that this reveals invisible creatures. The dust fades in 1d4 rounds plus one round per spell slot level. Thus, Glitterdust cast by a 3rd-level spell slot lasts for four to seven rounds. The material component is ground mica.
