EYEDUST EYEDUSTER

EYEDUSTER
  
  Composed of a small packet of rare salts from beyond Dune Sea then
hidden with spells, this trap when sprung hurls the caustic salts
and then guides them with spells right under the victim's eyelids. Masks,
helms, veil, and even gnome goggles are useless as defense against the
enchanted powders.  The unfortunate victim of this fairly difficult
to disarm trap may be left sightless for hours at end. As an added bonus 
the enchantments used on salts notify the creator when this trap is sprung
or defused.
