Your deep focus grants you a measure of control over your body.
Prerequisite: Wis 13, Arcane Focus.
Benefit: When you expend your arcane focus, you may select one of the following three benefits.
Overcome Distraction: You may ignore one of the following conditions for a number of rounds equal to your Wisdom bonus (minimum 1 round): fatigued, nauseated, shaken, or sickened. Alternatively, you may reduce exhausted to fatigued or frightened to shaken for an equal amount of time.
Slowed Breathing: Your breathing slows to imperceptible levels, allowing you to appear dead upon casual observation. Anyone examining you for signs of life must make a DC 20 Heal check or mistake your condition for death. In addition, you gain a +4 circumstance bonus on your Fortitude save to resist the effects of toxic fumes or inhaled poisons while your breathing is slowed. In addition, holding your breath for 1 minute only counts as 5 rounds of breath-holding.
Sudden Effort: You gain a +4 circumstance bonus to Strength, Dexterity, or Constitution (your choice) until your next turn. If you use this benefit more than once per day, you become fatigued. If you use this benefit while fatigued, you become exhausted.
Special: A wizard may select Body Awareness as a wizard bonus feat.
