You realize that one of your latent psychic wild talents is that of an ironman.

Combat

As you battle, something seems to rise up from within you, and suddenly as if
by instinct you find yourself turning your mind inward, sending a wave of
energy through you which fills you with a feeling of magnified strength and
endurance as it unlocks your body's hidden reserves.

Help File

  Ironmen possess the ability to unlock their body's hidden reserves of
strength and stamina, bringing to bear resources which normally lie hidden.
Moreover, while ordinary people may sometimes access these reserves in
extreme situations, they quickly exhaust whatever strength is available to
them there, while the psychic capabilities of an ironman allow him to
constantly renew his body, allowing him to function at enhanced levels of
performance for extended periods of time.

  To tap into your body's latent capabilities, concentrate on enhancing your
physique. Maintaining this state will tax your psychic energies; concentrate
on ceasing to enhance your physique in order to allow the effect to lapse.
Your facility with this power is determined by your willpower, your
perception, and your skill at redaction.
