Psi-Null Feats

Psi-Null feats are available only to characters and creatures with absolutely no ability to manifest psionic powers, do not have a power point reserve, and do not have any psi-like abilities. If a character gains any psionic ability, he immediately loses access to any psi-null feats he possesses.
