"ability to manifest powers of the normal maximum power level in at least one psionic class" --what does this mean?
I think it means that can cast power Lv 9 for Psion & Wilder, while Lv6 for Psychic Warrior, but when I made my level to Sorcerer5/Wilder5/Cerebremancer11 and took all Lv 9 powers, the psionic feats ''Expanded Knowledge' & 'Epic Expanded Knowledge' still didn't appear, and when I chose 'Epic Psionic Focus I' I was told that I haven't got the "ability to manifest powers of the normal maximum power level in at least one psionic class"... same things happened on Sorcerer/Psion
So how to get those feats available?
