Blues are by nature a mutation, variants of the original goblin stock, and some seek to elevate that mutation to an extreme. Mutators create a highly volatile mutagen capable of transforming their forms and altering their size.
The mutator’s mutagen is unusually volatile. The alchemical bonus to his selected physical ability score is instead 1d4+2 when he drinks the mutagen and the penalty to his corresponding mental ability score is 1d4+1. This increases to 1d6+3 via improved mutagen and 1d8+4 with greater mutagen, instead of the normal change to the alchemical bonus to physical ability score and penalty to mental ability score of those discoveries.
At 4th level, the mutator gains the combustible mutagen discovery, a unique discovery only available to him.
Combustible Mutagen: This discovery allows the mutator to fuel his mutagen with psionic power in order to become combustible. Anyone striking the mutator with a melee weapon while the mutator is under theeffects of this discovery takes 1d6 points fire damage. Creatures making melee attacks from more than 5 ft. away with reach weapons do not suffer this damage. At 8 th level and every four levels thereafter, this damage increases by an additional 1d6 points of fire damage. If the mutator dies from the attack, all creatures within 10 feet of the mutator take 1d6 of fire damage per 2 Hit Dice the mutator has as his body bursts in a fiery explosion.
At 6th level, the mutator has learned to take an extract he has prepared and convert its energy into an effect to alter his size. By mixing a prepared extract into his mutagen, the mutator can add an enlarge person or reduce person effect to that mutagen, although the original effect of the extract is wasted. The effect lasts for the duration of the mutagen and has a caster level equal to the alchemist’s level. However, once effect of the mutagen ends, the mutator takes 2 points of ability damage to Strength, Dexterity, and Constitution.
This ability replaces swift poisoning.
