Iron Will I-II
Rules: improve your Spirit by one per level (and suffer an action penalty of one per level) as long as you concentrate and remain focused. When in doubt, make a Self-Control check (see page 192). Iron Will has no effect if you go to sleep, receive the condition Unconscious, or stop concentrating. When the effect ends, you suffer a level of the condition Confusion (see page 32).
