Benefit(s): The alchemist can replace up to four of his own amputated limbs with those of a monstrous beast of the same size category. If the grafted limb is an arm, the alchemist gains either a climb speed of 15 feet or a claw or slam natural attack that deals 1d6 points of damage (1d4 for a Small alchemist).
If the grafted limb is a leg, the alchemist gains one of the following benefits: a +5 bonus to land speed, a swim speed of 15 feet, or a +5 bonus on Acrobatics checks when jumping. For each limb the alchemist replaces in this manner, he takes a –2 penalty to Wisdom as he loses his sense of self. Derros are immune to this penalty.
