Erudite

The Erudite is a variant on the Psion class for the 3.5 Edition of the Dungeons and Dragons RPG.

Characteristics

Instead of being merely self-conscious as the Psion, the Erudite follows a scholarly path to mastering psionic power. An Erudite can only manifest a certain number of unique powers from their repertoire every day, but unlike the Psion that repertoire is limited only by what the Erudite can learn.
