Type: Psionic
Source: Dragon #287
You can upgrade your powers.
Prerequisite: Any other psionic or metapsionic feat
Benefit: Choose one power chain from which you have learned a psionic power. When you learn a higher-level power on that chain, you can "forget" one or more lower-level powers you know on the chain, substituting new, different powers of the same lower level instead. If you "forget" a lower-level power and that is the only power you know from your discipline at that level, you must substitute another power from your discipline at that level. You can choose not to "forget" a lower-level power you know, even if learning a higher-level power on a chain for which you have chosen this feat.
Recognized power chains are described in Dragon #287, pages 55, 56 - other power chains may be possible (or the recognized power chains may be altered), at your DM's discretion
Special: You can gain this feat multiple times. Each time, it applies to a new power chain.
