The power to use abilities of a Homunculus. Variation of Cryptic Physiology and Artificial Physiology.


User with this ability either is or can transform into an homunculus (plural "homunculi"), a type of artificial human connected to Alchemy, from the Latin for "little man". Their traditional depiction is as tiny people grown in jars, but they tend to differ a lot in presentation. Homunculi generally act as a magician's assistant (a.k.a familiar), spy, messenger, or even assassin. They are capable of speech, though this is not always the case. If created correctly, they are loyal to a fault when it comes to their master.

As an artificial being, they lack many of the weaknesses of purely biological ones, and their creator may add other abilities depending of their skill.



As an artificial being, homunculi may have various abilities, especially those that include changing/manipulating their body or removing weaknesses, but various alchemical and/or supernatural abilities are possible.
