Prerequisites: Proficiency with the Occult skill and catalysts, mana, or psi
You can spend 10 minutes to perform a ritual to create a companion known as a homunculus. At the end of the ritual, the homunculus appears in an unoccupied space that you can see within 10 meters and assumes the form of a homunculus companion form.
Subtract an amount of catalysts or mana equal to your catalyst limit or mana limit, or an amount of psi equal to double your mana limit each time you take a rest. The homunculus is augmented to that amount of catalysts or mana. The homunculus is friendly to you and your companions and you always call the same homunculus.
As an action on each of your turns, you can mentally command your homunculus if it is within 100 meters of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what actions your homunculus will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, your homunculus only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete.
If the homunculus is ever slain, the magical bond you share allows you to return it to life. With 8 hours of work and the expenditure of 25 sp worth of rare materials, you call forth the homunculus’s spirit and use your magic to create a new body for it. You can return a homunculus to life in this manner even if you do not possess any part of its body.
