At 2nd level, the mutagenic form of the master chymist continues to evolve and develop as she grows in power. The master chymist selects an advanced mutagen, a power that changes how her mutagen form works or can only be accessed in her mutagenic form. She gains additional advanced mutagens at 4th, 6th, 8th, and 10th level. The chymist cannot select the same advanced mutagen more than once.
In her mutagenic form, the master chymist's heavy physical frame gives her an alchemical bonus on Strength checks, Constitution checks, and Strength-based skill checks as well as a bonus to CMB and CMD. The bonus is equal to half the master chymist's class level.
When in her mutagenic form, the chymist can temporarily change her appearance to her normal form and still retain most of the abilities of her mutagenic form. As a standard action, she may make a Will saving throw (DC 20) to assume the appearance of her normal form for one minute. Each additional minute beyond the first requires a new saving throw with a +1 increase to the DC. Failure means the chymist assumes her normal form (as if ending the use of mutagenic form) or reverts fully to her mutagenic form. At any time while using this ability, the chymist can resume her normal form as a standard action or relax her will and revert to her mutagenic form as a free action. Once this ability ends, the chymist cannot use it again until 10 minutes have passed. Obvious physical changes in mutagenic form such as draconic mutagen, feral mutagen, and growth mutagen do not work while the chymist is disguised in her normal form. Time spent disguised counts toward the chymist's time in her mutagenic form.
When the chymist assumes her mutagenic form, she gains dragon-like features—scaly skin, reptilian eyes, and so on, resembling a half-dragon. The chymist chooses one dragon type (see the draconic bloodline) when selecting this advanced mutagen; once selected, this choice cannot be changed and determines her draconic resistances and breath weapon type. The chymist gains resistance 20 to the dragon's energy type. The chymist's breath weapon deals 8d8 points of energy damage (Reflex half, DC 10 + the chymist's class level + the chymist's Intelligence modifier); she may use her breath weapon once per transformation into her mutagenic form. The character must have an effective alchemist level (alchemist level plus master chymist levels) of at least 16, must know the form of the dragon I extract, and must have the feral mutagen discovery or advanced mutagen to select this ability.
Dual Mind
The chymist's alter ego gives her a +2 bonus on Will saving throws in her normal and mutagenic forms. If she is affected by an enchantment spell or effect and fails her saving throw, she can attempt it again 1 round later at the same DC; if she succeeds, she is free of the effect (as if she had made her original save) and immediately changes to her mutagenic form or back to her normal form. If she has no more uses of the mutate ability remaining for the day, she cannot use dual mind. The character must have an effective alchemist level (alchemist level plus master chymist levels) of at least 10 to select this ability.
This mutagen functions as the rogue ability of the same name, except that it only applies in the chymist's mutagenic form.
The duration of the master chymist's mutation is doubled.
This mutagen is identical to the alchemist discovery of the same name and counts as that discovery for the purpose of qualifying for other discoveries or advanced mutagens.
The damage dice for the feral mutagen's bite and claw attacks increase by one die step. The character must have an effective alchemist level (alchemist level plus chymist level) of at least 11 and must have the feral mutagen discovery or advanced mutagen to select this ability.
This mutagen is identical to the alchemist discovery of the same name and counts as that discovery for the purpose of qualifying for other discoveries or advanced mutagens. The character must have an effective alchemist level (alchemist level plus master chymist levels) of at least 16 and must have the feral mutagen discovery or advanced mutagen to select this ability.
This mutagen is identical to the alchemist discovery of the same name and counts as that discovery for the purpose of qualifying for other discoveries or advanced mutagens. The character must have an effective alchemist level (alchemist level plus chymist level) of at least 12 and must have the feral mutagen discovery or advanced mutagen to select this ability.
When the chymist assumes her mutagenic form, she increases one size category, as if under the effects of an enlarge person spell. The character must have an effective alchemist level (alchemist level plus chymist level) of at least 16 and must know the enlarge person, giant form I, or polymorph extract to select this ability.
The chymist gains darkvision 60 feet and low-light vision in her mutagenic form.
The master chymist's lithe physical frame gives her an alchemical bonus on all Dexterity checks, Dexterity skill checks, and CMD, and a natural armor bonus to her Armor Class. The bonus is equal to half the master chymist's class level.
When the chymist assumes her mutagenic form or returns to her normal form from her mutagenic form, she heals a number of hit points equal to 1d8 + her character level.
The master chymist gains the scent ability in her mutagenic form.
