oak body
Class: psywarrior : 5 psion : 7
Syntax: cast CLASS oak body

By using this power, the psionic character lends some of his psychic energy to

     protect himself. It causes the manifester to gain some resistance to physical attacks, as well as immunity 
     to most standard poisons. The oaken nature of the power leaves the manifester 
     vulnerable to fire attacks. The oaken body brings a minor bonus to strength at the cost of dexterity. 
     This power does not work together with Stoneskin or Iron Body.
