I am a beginning in the long process of character creation. Of all my choices, the Psion (telepath) appeals to me most. However, I have a couple big concerns. The first is that by utilizing a non-standard character that requires a supplement, many DMs are not going to want me in their game. The second concern is that it would completely exclude me from any D&D 4E games, which I would also like to learn how to play. Does anyone have any good advice for me?
