Maskstone (Reversible)

This spell alters the appearance of stone to hide seams, openings, traps, runes, doors, and so on. The priest touches the central point of the area to be masked, and visualizes what appearance is desired (hue, fissures, shape, and general appearance). The spell cloaks the stone with the visualized, long-term illusion. A caster of at least 6th level can cloak a second section of similar dimension, and a caster of at least 9th level, a third section.

Features of the stone under the maskstone spell remain physically unchanged. A known door can be felt for and located in 1d3 rounds. Unless it has been used by the searcher before, determining its method and direction of opening and the location of any locks or catches is extremely difficult without a dispel magic spell to end the cloaking effect. Only characters with thieving skills have the necessary expertise. These can find catches, locks, and traps on such doors at a -15% penalty to their find trap rolls; unlock locks at a -10% penalty to their open lock rolls; and remove found traps at a -10% penalty to their remove trap rolls.

A dwarf, duergar, gnome, xorn, or other subterranean dweller can tell by examination that the stone's surface has been magically masked, but not the nature of the true surface. Features affixed to the stone's surface (such as maps or inscriptions) are hidden by this magic. True seeing penetrates the spell.

The material components are an eyelash (from any creature) and a pinch of dust or sand.

The reverse of this spell, reveal stone, negates maskstone. If not used for this purpose, it clearly indicates secret or hidden doors, panels, cavities. storage niches, catches, locks, and other deliberately hidden features by momentarily illuminating them with a glowing outline. These features are revealed if the stone has a maskstone spell on it or if it is simply in poorly-lit or confusing natural conditions.

The reverse of the spell requires a scrap of gauze and a piece of phosphorous or a handful of iron filings.
