Mutators specialize in creating highly specialized mutagens, called evolutionary catalysts, that confer unusual abilities. Due to the often highly visible nature of the powers bestowed by evolutionary catalysts, the alchemist also develops techniques to disguise his true identity and allow him to continue his experiments unmolested.
A mutator’s mutagen is referred to as an evolutionary catalyst. Instead of granting an alchemist bonuses to a physical ability score and natural armor and a penalty to a mental score, his mutagen instead grants him a pool of spell points equal to 1/2 his class level (minimum 1) and a single Mutation vigilante talent of his choice, chosen at the time he brews the evolutionary catalyst. Any unused spell points granted by this ability are lost when the mutagen expires. For the purposes of determining the effects of mutations gained from his mutagen and what mutations the alchemist qualifies for, the alchemist is treated as having a caster level and vigilante level equal to his class level, and uses his Intelligence as his casting ability modifier. The mutator cannot take the cognatogen discovery, mutagen discovery, nor any discoveries that have those as prerequisites.
This alters but otherwise counts as the mutagen class feature, and replaces the poison use, poison resistance, and poison immunity class features.
Starting at 1st level, the mutator gains the vigilante’s dual identity class feature. A mutator who uses the abilities granted by his evolutionary catalyst while in his social identity risks exposing his secret.
This replaces the brew potion class feature.
