Components: V, S
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)

Duration: 1 min./level; see text
Saving Throw: Will negates (blinding only)

A burst of golden particles covers everyone and everything in the area.

Creatures within the area become blinded and easier to see. Any creature covered by the dust takes a -40 penalty on Hide checks, and is visibly outlined even if invisible. A successful will save negates the blindness.

The dust can be removed (ending the spell with respect to one object or creature) as a full-round action that provokes attacks of opportunity.

The initial burst itself is instantaneous, but the creatures and objects caught in it suffer the effects for the duration of the spell.
