The alchemist's cognatogen now grants a +6 natural armor bonus, a +8 alchemical bonus to one mental ability score (Intelligence, Wisdom, or Charisma), a +6 alchemical bonus to a second mental ability score, and a +4 alchemical bonus to a third mental ability score. The alchemist takes a –2 penalty to his Strength, Dexterity, and Constitution as long as the cognatogen persists, and takes 2 points of ability damage to each physical ability score when the cognatogen ends. An alchemist must be at least 16th level and must have the greater cognatogen discovery or class ability before selecting this discovery.
