Conjuration (Creation)
Level: Mage 2; Components: V, S, M; Casting Time: Attack action; Range: Medium (100 ft. + 10 ft./level); Area: Creatures and objects within 10-ft. spread; Duration: 1 round/level; Saving Throw: Will negates (blinding only); Spell Resistance: Yes
A cloud of particles covers everyone and everything in the area, blinding creatures and visibly outlining invisible things 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 Defense, grants a +2 bonus on opponents' attack rolls (they are effectively invisible), moves at half speed, and suffers a -4 penalty on Search checks and most Strength- and Dexterity-based skill checks.
