This spell guards the spell recipient against magical or psionic attacks that affect the mind. This includes beguiling, charm, domination, feeblemind, Basic Hold, and similar effects, as well as most telepathic psionic powers and attacks. Against magical influences, impregnable mind grants a +4 bonus to saving throws; if the attack normally allows no saving throw, the spell recipient may attempt one at no modifier. Against telepathic psionics, the spell inflicts a –6 penalty to the attacking psionicist’s power checks, making it more likely that a psionic attack or telepathic contact will fail.Impregnable mind offers no protection against nontelepathic psionics, such as a telekinetic thrashing or other psionics that affect the body.
