Mind Over Matter
Mind over matter [minor] by Iczer
"Yeah, you can call me puny, but I'm telling you it's my brain that does the work here"
The character has the literal ability to bend his own body to his will. while conscious and awake/aware, he may substitute his ME for his PS score and treat this adjusted PS as extraordinary. During this time, he may also enjoy a type of force field, granting him an AR of 8, plus a SDC bonus equal to MEx2. He may substitute his ME for PE as well, but doing so robs him of his PS and SDC bonuses for that melee round. While asleep, distracted or otherwise unaware, his PS/SDC/PE reverts to normal. If afflicted with any sort of mind affecting assault, his PS/PE/SDC drops as well (this includes a failed HF check as well as some psychic/magic attacks. benign effects do not affect it)
Other bonuses: Gains +1 ME every level, and a one time bonus of +1d4 IQ.
