  The body of the target creature gains a metabolic response that allows it to benefit from normally deadly toxins. When a poison would cause Ability Damage to the target creature, the target instead gains a +4 Alchemical Bonus to that ability score. The spell then immediately ends, but the bonus lasts for a number of minutes equal to the amount of Ability Damage the poison would have caused. If the poison would deal more than one type of Ability Damage, each bonus has a separate duration. If the poison has effects other than Ability Damage (such as unconsciousness or Ability Drain), these effects apply normally. This spell affects only a single poison; if multiple poisons affect the target simultaneously, this spell prevents only Ability Damage and grants the appropriate bonuses for the poison that would cause the most damage.
