A cloud of glittering golden particles covers everyone and everything in the area, blinding creatures and visibly outlining invisible things. Blindness lasts for the duration of the spell. All within the area are covered by the dust, which cannot be removed and continues to sparkle until it fades.
In addition to the obvious effects, a blinded creature suffers a 50% miss chance in combat (all opponents have full concealment), loses any Dexterity bonus to AC, grants a +2 bonus to opponents’ attack rolls (they are effectively invisible), moves at half speed, and suffers a –4 penalty on most Strength- and Dexterity-based skills.
