Alchemy

Spells Gained:
Alchemy Philosophers do not gain additional spells to their list, however they gain an additional extract slot at each level. This stacks with the Alchemy ability, totaling an additional 2 extract slots at each spell level.

Mutagen Effects:
An alchemy Philosopher has mastered their mutagen through intense study. They may choose their ability bonus and penalty freely when the mutagen is created. The two are not tied as an Alchemist’s mutagen is.

At 5th level your mutagen can apply Alter Self or Beast Shape I to you for its duration. You may change forms as a full round action. This also is treated as a transmutation (Polymorph) extract for the purpose of other abilities.

At 10th level the available forms include Fey Form I, Monstrous Physique I, Vermin Shape I, and Undead Anatomy I.

At 15th level the available forms include Fey Form II, Monstrous Physique II, Vermin Shape II, Undead Anatomy II, and Beast Shape II.

At 20th level the available forms include Fey Form III, Monstrous Physique III, Giant Shape I, Undead Anatomy III, and Beast Shape III.

Mutation (Su):
At 3rd level you may apply two extracts of the Polymorph school to yourself. On using the second extract you do not change form but you can choose to gain one of the special features granted by the extract used (Not ability scores, size changes, or attacks).

Shifting Form (Su):
At 6th level whenever you’re under the effects of a transmutation extract you may alter the extract. In doing this you change the chosen extract into another of the same level, having incremented the duration down by the appropriate amount (Ex If you start with a 10 min/level duration at level 6, use up 40 minutes, and then change to a 1 round/level duration you only benefit for 2 rounds). You may do this once per day.

Lingering Transformation (Su):
At 9th level your transmutations linger much longer than normal. Extracts are always treated as if under the effects of Extend Spell without increasing their level. If an extract with a duration measured in rounds is used by you it instead has a duration in minutes, and is not affected by extend spell.

True Polymorph (Su):
At 15th level whenever you are affected by a transmutation extract that is not from your mutagen you may spend the entire duration in a rubbery cocoon. During this process you are helpless and must make a Fort save equal to that of the spell or suffer ability drain equal to the spell level to all your physical scores. If you succeed you instead adopt a form granted by the effect as your new natural form. This does not grant HD or abilities not granted by the extract, however it does persist after death and through antimagic fields. You may change your form in this way once per month. Any fast healing or regeneration granted by the transmutation does not apply to this new form. You may only have one extract altering your true form at a time. If you polymorph into a creature normally unable to brew extracts you instead become able to brew one at each extract level. Polymorphs change your equipment to fit your new form regardless of the normally effects of the extract, they do not merge with your body. Your type changes accordingly.
