Heighten Power [Metapsionic]
Benefit: A heightened power has a higher psionic power level than normal (up to 9th level). Unlike other metapsionic feats, Heighten Power actually increases the effective level of the power that it modifies. All effects dependent on power level (such as saving throw DCs and ability to penetrate a minor dead psionics zone or a minor globe of invulnerability) are calculated according to the heightened level. The heightened power costs as many power points as a power of its effective level.
