实验员（侠客职业变体）出自惧怖冒险（Horror Adventures）70页Experimenter（Vigilante Archetype）一些侠客为了从公众视野中隐藏他们怪异的实验而选择活在秘密之中。PFS：实验员在3级和11级时获得技能专攻（手艺（炼金术）（Craft(Alchemy)），易容（Disguise）或知识（工程）（Knowledge(engineering)））作为奖励专长，代替制造药水（Brew Potion）和制造构装体（Craft Construct）。
本职技能（Class Skills）：实验员将所有的知识（Knowledge）技能加入他的本职技能列表中。
这个能力改变（Alters）了侠客的本职技能。武器和防具擅长（Weapen and Armor Proficiencies）：实验员不擅长军用武器，中型盔甲以及盾牌。
这个能力改变（Alters）了侠客的武器和防具擅长。禁忌科学（Forbidden Science, Ex）：实验员在知识（工程）（Knowledge(Engineering)）和用于制作炼金物品的手艺（炼金术）（Craft(Alchemy)）检定上获得等同于1/2侠客等级的加值（至少+1）。他也知晓如何像一名等同于他职业等级的炼金术士（Alchemist）一般制作突变药剂（Mutagen）
APG。他能够选择一项炼金术士科研发现（Discovery）代替他获得的侠客天赋（Vigilante Talent），但只能选择那些影响突变药剂的发现（包括异变药剂(Cognatogen)UM科研发现）。
当实验员陷入困惑（Confused）,晕眩（Dazed），惊惧（Frightened），恐慌（Panicked）或震慑（Stunned）时，他必须在每次他的回合开始时尝试进行一次意志检定（DC=20+他的侠客等级）。如果他失败了，他立即如同使用了他的突变药剂一般进行突变（随机决定能力赋予的加值）。这并不会消耗他的突变药剂，效果只会持续等同于3+他的侠客等级的轮数，并且在突变结束之后他会变得疲乏。以这种方式进行突变时，他会陷入困惑，并且重骰任何“正常行动（Act Normally）”的结果。这个困惑效果是突变药剂带来的突变的一部分，那些防止或移除困惑效果的能力无法适用于该效果，然而那些能够终止突变药剂影响的效果会正常运作。他会忘记在处于这种偶然性的突变期间经历的一切。
这个能力取代（Replaces）侠客之道（Vigilante Specialization）。诱发变身（Mutagenic Change, Ex）：以一个整轮动作，实验员能够使用他的突变药剂并从他的社交身份（Social Identity）转变为侠客身份（Vigilante Identity），如同他拥有
快速变装（Quick Change）社交天赋（Social Talent）。
这个能力取代（Replaces）1级时获得的社交天赋（Social Talent）。制造药水（Brew Potion）：在3级时，实验员获得
制造药水（Brew Potion）作为奖励专长。他能够将他的侠客等级视作施法者等级并使用手艺（炼金术）（Craft(Alchemy)）代替制造药水所需的法术辨识（Spellcraft）。他能够使用另一瓶含有同样法术的药水作为样本来提供制作药水所必须的法术，这个行为不会消耗这瓶药水并会导致制造DC上升5。
这个能力取代（Replaces）不可动摇（Unshakeble）。博学（Lore Master, Ex）：在5级时，实验员获得
博学（Lore Master）吟游诗人（Bard）职业能力。
这个能力取代（Replaces）惊愕现身（Startling Appearance）。制造构装体（Craft Construct）：在11级时，实验员获得
制造构装体（Craft Construct）作为奖励专长。他将他的侠客等级视作施法者等级并使用知识（工程）（Knowledge(Engineering)）代替制造构装体所需的法术辨识（Spellcraft）。
这个能力取代（Replaces）骇人现身（Frightening appearance）。不定突变（Mutable Mutagen, Su）：在17级时，实验员的突变药剂的持续时间增加至每等级1小时。
这个能力取代（Replaces）震撼现身（Stunning appearance）。劇透 - 原文:
EXPERIMENTER (ARCHETYPE)
Some vigilantes adopt lives of secrecy to hide their strange experiments from public view.
Class Skills: An experimenter adds all Knowledge skills to his list of class skills.
This alters the vigilante’s class skills.
Weapon and Armor Proficiencies: Experimenters aren’t proficient with martial weapons, medium armor, or shields.
This alters the vigilante’s weapon and armor proficiencies.
Forbidden Science (Ex): 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 mutagenAPG 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 cognatogenUM 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.
Mutagenic Change (Ex): As a full-round action, an experimenter can consume his mutagen (if he has one) and shift from his social identity to his vigilante identity, as if he had the quick change social talent. This ability replaces the 1st-level social talent. Brew Potion: 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.
Lore Master (Ex): At 5th level, an experimenter gains the lore master bard class feature. This ability replaces startling appearance. Craft Construct: At 11th level, an experimenter gains Craft Construct as a bonus feat. He treats his vigilante level as his caster level and can use Knowledge (engineering) instead of Spellcraft to craft a construct.
This ability replaces frightening appearance.
Mutable Mutagen (Su): At 17th level, the duration of an experimenter’s mutagen increases to 1 hour per level.
This ability replaces stunning appearance.
