引述：闹鬼英雄手册《Haunted Heroes Handbook》炼金术师变体-炼魂士(Ectoplasm Master)『....开什么玩笑！...炼成贤者之石的原料...居然是活人的灵魂.....』
——爱德华·艾尔利克《钢之炼金术师》炼魂士拥有把可怖幽灵蒸馏成炼金试剂的奇异能力，这种怪异技术的起源乃是来自默语魔道的特工们。然而自从被叛逃到巴拉丁之眼秘会之中的成员把这个秘密暴露出去后，该技艺就风一样地传遍了各地。如今，炼魂士已经不会像以前那样被自动当作是心术不正的危险分子了。炼灵合成（Ectoplasmic Extracts，Su）：炼魂士并非通过炼金试剂来制造炼金物品，包括炸弹，化合炼成和突变药剂等，而是利用诸如骨灰，灵质晶体，以及类似炼金催化剂那样的试剂作为原料。就跟标准炼金术师一样，这些材料的花费可以忽略不计，这点和大部分法术的廉价施法材料一样。由于这种技术本身和涉及的炼金原料都相当诡异，炼魂士的公式列表得到了拓展。他可以把所有术士/法师6环及以下死灵学派的法术加到自己的公式列表里，但仍需对应进行学习抄写后才能使用。如果有法术同时出现在炼金术师公式列表和术士/法师法术列表里面，则炼魂士使用两者间环级较低的那个版本。
这项能力调整了化合炼成并替代制造药水。炼灵科研（Ectoplasm Master Discoveries，Su）：炼魂士除了正常的炼金术师科研发现外，能选择下列科研：
灵质突变（Ectoplasmic Mutagen）：任何时候，炼魂士在服用突变药剂后，他的肉胎凡躯转化成了灵界异质，因此身体呈现半流质的形态，此时他没法获得天生护甲加值。然而在突变药剂生效期间，炼魂士对重击和偷袭等精准伤害免疫。至少需要6级炼魂士等级才能选择这一科研发现。
灵质仆从（Ectoplasmic Servant）：选择该科研的炼魂士可以把所有6环及以下的召唤怪物法术加入到公式列表里面，并作为炼灵合成使用。任何适合，只要他通过炼灵合成召唤单一生物，该生物必须出现在与他邻接的方块之中，并且获得灵质生物模板(Pathfinder RPG Bestiary 4 82页)。通过炼灵合成召唤而来的生物除灵质生物模板外无法获得其他生物模板。
虹吸炸弹（Siphon Bomb）：炼魂士能调整炸弹，可以使作祟和虚体不死生物的灵质能量结晶无力化。虹吸炸弹对虚体生物造成全额伤害，就像力场效果一样，但是对实体生物只能造成非致命伤害。虹吸炸弹同样能对作祟造成伤害，但爆炸点必须在作祟区域内才能生效。这项科研调整了炼金术师的炸弹，并且无法和其他调整了炸弹效果的科研叠加。

Ectoplasm Master(Alchemist Archetype)
Able to distill spectral horrors into alchemical reagents, the eccentric techniques of the ectoplasm master originated among agents of the Whispering Way, though their secrets have since been exposed and spread to the winds by their rivals in the Esoteric Order of the Palatine Eye. Today, the ectoplasm master is not automatically regarded as an agent of sinister evil as a result.
Ectoplasmic Extracts (Su): Instead of using alchemical reagents in order to create alchemical items (including his bombs, extracts, and mutagens), an ectoplasm master uses reagents such as corpse dust, crystallized ectoplasm, and similar reagents as alchemical catalysts. Just as with standard alchemists, the costs of these materials are insignificant and are comparable to the costs of the valueless material components of most spells. As a result of his eccentric techniques and use of odd alchemical components, an ectoplasm master has an expanded formula list. He adds all sorcerer/wizard spells of 6th level or lower from the necromancy school to his alchemist formula list (but must still learn each of these spells normally). If a spell appears on both the alchemist formula list and the sorcerer/wizard spell list, the ectoplasm master uses the lower of the two spell levels listed for the spell. This ability alters extracts and replaces Brew Potion.
Ectoplasm Master Discoveries (Su): An ectoplasm master is able to select the following alchemist discoveries, in addition to general discoveries.
Ectoplasmic Mutagen: Whenever the ectoplasm master imbibes a mutagen, his living flesh transmutes into ectoplasm, causing him to take on a semiliquid form. He no longer gains a natural armor bonus from his mutagen, but instead becomes immune to critical hits and precision damage (such as sneak attacks) while under the mutagen’s effects. An ectoplasm master must be at least 6th level to learn this discovery.
Ectoplasmic Servant: An ectoplasm master who selects this discovery adds all summon monster spells of 6th level or lower to his alchemist formula list as ectoplasmic extracts. Whenever he summons a creature using an ectoplasmic extract, the creature must appear in a square adjacent to his own, and it gains the ectoplasmic creature template (Pathfinder RPG Bestiary 4 82). Creatures summoned using ectoplasmic extracts cannot have templates other than the ectoplasmic creature template.
Siphon Bomb: The ectoplasm master’s bombs can be modified to neutralize and crystallize the ectoplasmic energy of haunts and incorporeal undead. A siphon bomb deals full damage to incorporeal creatures as if it were a force effect, but deals only nonlethal damage to corporeal creatures. A siphon bomb also damages haunts, provided the siphon bomb explodes within a haunt’s area of effect. This discovery modifies the alchemist’s bombs and doesn’t stack with other discoveries that modify bombs.
