Greater Cognatogen

Feats

The alchemist's cognatogen now grants a +4 natural armor bonus to AC, a +6 alchemical bonus to one mental ability score (Intelligence, Wisdom, or Charisma), and a +4 alchemical bonus to a second mental ability score. The alchemist takes a –2 penalty on both associated physical ability scores as long as the cognatogen persists, and takes 2 points of ability damage to both associated physical ability scores when the cognatogen ends.
