Grand Mutagen

Feats

The alchemist's mutagen now grants a +6 natural armor bonus to AC, a +8 alchemical bonus to one ability score (Strength, Dexterity, or Constitution), a +6 alchemical bonus to a second physical ability score, and a +4 alchemical bonus to a third physical ability score. The alchemist takes a –2 penalty to Intelligence, Wisdom, and Charisma as long as the mutagen persists.
