Metamind and Slayer

From the publisher's website: A Web Enhancement for If Thoughts Could Kill Bruce Cordell has been promising psionics fans here at montecook.com that he would present a new take on the prestige classes from his Psionics Handbook. Here are the four alternate classes, just in time for you to use in If Thoughts Could Kill. These alternates integrate some new ideas of Bruce's with other class-building thoughts that developed while he was designing the sourcebook Tome and Blood last year. In these versions, he's altered some classes more than others, with the metamind the most changed of the four.
