Duerran Stealth Training
( Champions of Valor, p. 29)[Psionic]
Your studies have shown you the way to link your psionics and your invisibility spell-like ability.
Prerequisite
Gray dwarf,
Benefit
You can expend 5 power points to activate your invisibility spell-like ability. Though the triggering energy is psionic (and thus can't be initiated where psionics is unavailable), all other effects work like standard spell-like abilities. Note: This psionic technique was created by the gray dwarf worshipers of Deep Duerra, but other duergar (including exiles) have developed it independently.
