how about a alchemy skill you dont need to waste energy but you have to buy some of the equitment you could make a pet homucolus or any thing you want to make like a hat or peice of furinture but not crown items houses or mounts
A medieval chemical philosophy having as its asserted aims the transmutation of base metals into gold, the discovery of the panacea, and the preparation of the elixir of longevity.
A seemingly magical power or process of transmuting: "He wondered by what alchemy it was changed, so that what sickened him one hour, maddened him with hunger the next"
With this in mind I don't think your idea is the best. Alchemy is usually referred to as potion making. or making of elixirs. I hope this helps!
