Some vigilantes adopt lives of secrecy to hide their strange experiments from public view.
An experimenter adds all Knowledge skills to his list of class skills.
This alters the vigilante’s class skills.
Experimenters aren’t proficient with martial weapons, medium armor, or shields.
This alters the vigilante’s weapon and armor proficiencies.
An experimenter gains a bonus equal to 1/2 his vigilante level on Craft (alchemy) checks to create alchemical items and on Knowledge (engineering) checks (minimum +1). He also learns how to craft a mutagen as if he were an alchemist of his class level. He can take alchemical discoveries in place of vigilante talents, but only discoveries that affect his mutagen (including cognatogen discoveries).
When an experimenter is confused, dazed, frightened, panicked, or stunned, he must attempt a Will save (DC = 20 + his vigilante level) each round at the start of his turn. If he fails, he transforms as if he had consumed his mutagen (determine which ability score gets the bonus randomly). This doesn’t consume his mutagen, and lasts a number of rounds equal to 3 + his vigilante level, after which the transformation ends and he becomes fatigued. While transformed in this way, he is confused, and he rerolls any result of “act normally.” Since the confusion is part of the mutagenic transformation, abilities that prevent or remove confusion don’t apply to this effect, though abilities that end the effect of a mutagen work normally. He forgets everything that happened while he was involuntarily transformed.
This ability replaces vigilante specialization.
This ability replaces the 1st-level social talent.
At 3rd level, an experimenter gains Brew Potion as a bonus feat. He treats his vigilante level as his caster level and can use Craft (alchemy) instead of Spellcraft to brew potions. He can use another potion of the same spell as a sample to provide the necessary spell without consuming the potion, increasing the DC by 5.
This ability replaces unshakable.
This ability replaces startling appearance.
This ability replaces frightening appearance.
At 17th level, the duration of an experimenter’s mutagen increases to 1 hour per level.
This ability replaces stunning appearance.
