Weapon and Armor Pro?ciency: Cerebremancers gain no pro?ciency with any weapon or armor.

Spells per Day/Powers Known: When a new cerebremancer level is attained, the character gains new spells per day as if he had also attained a level in any one arcane spellcasting class he belonged to before he added the prestige class. He gains additional power points per day and access to new powers as if he had also gained a level in any one manifesting class he belonged to previously. He does not, however, gain any other bene?t a character of either class would have gained (bonus metamagic, metapsionic, or item creation feats, psicrystal special abilities, and so on). This essentially means that he adds the level of cerebremancer to the level of whatever other arcane spellcasting class and manifesting class the character has, then determines spells per day, caster level, power points per day, powers known, and manifester level accordingly.

For example, a 3rd-level wizard/3rd-level psion who takes a level in cerebremancer has the same access to spells as a 4th-level wizard and the same number of power points as a 4th-level psion. But his wizard familiar and his psicrystal (if he has one) won’t gain any new abilities.

If a character had more than one arcane spellcasting class or more than one manifesting class before he became a cerebremancer, he must decide to which class he adds each level of cerebremancer for purpose of determining spells per day, caster level, power points per day, powers known, and manifester level.
