As a manifester's knowledge of psionics grows, he can learn to manifest powers in ways slightly different from how the powers were originally designed or learned. Of course, manifesting a power while using a metapsionic feat is more expensive than manifesting the power normally.
Manifesting Time: Powers manifested using metapsionic feats take the same time as manifesting the powers normally unless the feat description specifically says otherwise.
Manifestation Cost: To use a metapsionic feat, a psionic character must both expend his psionic focus (see the Concentration skill description) and pay an increased power point cost as given in the feat description.
Limits on Use: As with all powers, you cannot spend more power points on a power than your manifester level. Metapsionic feats merely let you manifest powers in different ways; they do not let you violate this rule.
Effects of Metapsionic Feats on a Power: In all ways, a metapsionic power operates at its original power level, even though it costs additional power points. The modifications to a power made by a metapsionic feat have only their noted effect on the power. A manifester can't use a metapsionic feat to alter a power being cast from a power stone, dorje, or other device.
Manifesting a power modified by the Quicken Power feat does not provoke attacks of opportunity.
Some metapsionic feats apply only to certain powers, as described in each specific feat entry.
Psionic Items and Metapsionic Powers: With the right psionic item creation feat, you can store a metapsionic power in a power stone, psionic tattoo, or dorje. Level limits for psionic tattoos apply to the power's higher metapsionic level.
A character doesn't need the appropriate metapsionic feat to activate an item in which a metapsionic power is stored, but does need the metapsionic feat to create such an item.
