Level: Mage 3; Components: S; Casting Time: Attack action; Range: Starship Tactical
(1,000 ft. + 500 ft./level); Target: One starship of Medium weight size or smaller; Duration: Concentration, up to 1 round/level; Saving Throw: Will negates (harmless) (object); Spell Resistance: Yes (harmless) (object)
The targeted starship has total concealment for the duration of the spell. To attack a starship under the effects of this spell, an attacker must guess in which square the starship currently is (or determine its position based on where it attacked last), and even if the guess is accurate, there is a 50% chance that the attack misses.
This spell supercedes the effects of a sensor jammer, stealth screen, or cloaking screen that may already be activated on the targeted starship.
