··· True Adaptation:  This potent technique allows the Psion to create certain changes within his body that render him all but immune to one form of attack.

 

System:  Roll Psi and spend a point.  For the next Psi turns (Psi minutes at Adaptation 5), the Psion gains a +1 Soak / success rolled vs one specific form of attack.  The attack form adapted to could be hand to hand bashing attacks, laser weapons, sonics, lasers / electricity, bullets / flechettes, toxins or even large slashing / impaling attacks.  Each requires certain adjustments to the characters physique and they are not particularly useful against other attack forms on the list.
