Psiforged Body( Magic of Eberron, p. 51)
As a warforged, your body can be crafted using trace amounts of psionically resonant deep crystal, providing you with increased psionic power and the ability to store psionic energy in your body. If you take this feat, you will often be referred to as a psiforged. For more information on the psiforged and their outlook, see page 39.
1st level only, Warforged,
You gain 1 extra power point at 1st level, regardless of whether you choose a psionic class. As you gain experience, you can attune the crystals infused in your body to the psionic energies of your mind. You can treat your body as a cognizance crystal, storing up to 1 power point plus 1 power point per two character levels (up to a maximum of 11 power points at 20th level), and withdrawing those stored power points at some later time. For more details on cognizance crystals, see page 167 of the Expanded Psionics Handbook.
Unlike most feats, this feat must be taken at 1st level during character creation.
