You can trade in powers from your primary discipline for additional powers.
Prerequisite: Manifester level 3rd+.
Benefit: When you gain a power from your primary discipline, you can trade it in for up to three powers of a lower level. New powers must be from your primary discipline. The total levels of the powers you choose cannot exceed the level of the power you traded in. Any 0-level powers count as 1st level for purposes of this feat. For example, at 18th-level a psion could trade in the 9th- level power he or she receives from his or her primary discipline for a 5th-level power, a 3rd-level power and a 1st-level power.
