Psion Handbook

[Noedig]

Does it exist? I would very much like to know if there is a compilation of useful knowledge on psions.

Google is your friend, you know. I found this (http://community.wizards.com/go/thread/view/75882/19571514/3.5_Psion_Buildguide_and_Compendium) with minimal effort, couldn't speak to whether the advice is good though.

Well, there's this one (http://brilliantgameologists.com/boards/index.php?topic=10238.0), and this one (http://brilliantgameologists.com/boards/index.php?topic=8342.0), and I'm working on one for Psionic Tricks (http://www.giantitp.com/forums/showthread.php?p=9867738#post9867738). So yeah, to answer your question, there are Psion Handbooks.
