The Final Metamorphosis — Walkthrough

Class Skills: Acrobatics, Bluff, Climb, Disguise, Fly, Handle Animal, Intimidate, Knowledge (nature), Perception, Ride, Sense Motive, Sleight of Hand, Stealth, Survival, and Swim. Skill Ranks Per Level: 4 + Int modifier.

Metamorph Table: Details base attack bonus, saves, and special abilities gained at each level from 1 to 20. Key abilities include Morphic Pool, Biophage, Unstable Stability, Rapid Mutation, Evolutionary Advantage, Fleshy Mass, Horror, Apex, and the final ability 'From a Single Cell' at level 20.

Weapon and Armor Proficiency: Proficient with all natural attacks. Not proficient with armor.

Morphic Pool: An innate pool of bioenergy fueled by consuming biomass. Maximum pool size equals class levels + permanent Constitution modifier. Spending pool points is a free action.

Biophage: Ability to consume biomass from helpless or recently deceased creatures to regain 1 point to the morphic pool per round of consumption. This ability does not work on creatures smaller than Tiny and is never considered an evil act.

Unstable Stability: A +4 bonus on saves vs. spells of the polymorph subschool.

Rapid Mutation: Allows the metamorph to grow grotesque weapons by spending morphic pool. Mutations last for 10 minutes. A metamorph can safely mutate 1 morphic pool point per round, or 2 points when bracing (swift action). Exceeding the limit inflicts 1 point of Con damage. At level 11, bracing allows 3 safe points. Mutations are suppressed under polymorph spells. The number of natural attacks is limited by level, starting at 3 at level 1 and increasing to 10 by level 17.

1-Point Mutations: Includes a Bite attack (1d6 damage, 1d8 if Large, 2d6 if Huge), which is a primary attack. If a bite already exists, this mutation enhances it.
