Powers: The psion's manifester level is equal to his class level. The psion's base power points do not increase after 20th level. Each time the psion attains a new level, he learns two new
powers of any level or levels that he can manifest.
Psicrystal: The epic psion's
psicrystal, if he has one, continues to increase in
power. At every odd-numbered level higher than 20th (21st, 23rd, and so on) the
psicrystal's natural
armor bonus and Intelligence each increase by 1. The
psicrystal's
power resistance is equal to the master's level + 5. At 21st level and again every ten levels higher than 21st, the
psicrystal gains the benefit of the
Psicrystal Power epic feat for a power of its master's choice.
