Tower of Mental Resistance

This spell wards the caster's mind against mental attack, creating a barrier much like the psionic defense mode, tower of iron will. A creature attacking psionically must breach the lower before its telepathic attacks can affect the protected wizard. The lower also protects anyone standing within three feet of the protected wizard.

The tower of mental resistance is empowered with 1d4 psionic strength points (PSPs) per caster level, to a maximum of 20d4. These points are not expended until the wizard is psionically attacked. The tower of mental resistance remains in force until its strength is exhausted, to a maximum of 24 hours. Casting another such spell restores a partially depleted tower to full strength (reroll PSPs), and extends the maximum duration to 24 hours from the time of the casting.

When the wizard is attacked psionically, the tower of mental resistance instantly becomes active (attempting any telepathic science or devotion against the wizard counts as an attack). Each round that the wizard is attacked, the tower expends 6 PSPs. When the tower runs out of PSPs, the protection fails. The caster can end the spell at any time by an act of will. Any psionic powers the caster may have are rendered unusable as long as the tower of mental resistance remains in effect.
