I'm trying to help you L. I really am, but there isn't really a way to do this without killing off yourself as well from too much life being used. You'd pretty much have to be chanting your entire life to keep it like that.
Converting an actual person into a doll wouldn't work because they'd have to give you permission to use their lifeforce. Then even if you got that, the Magic being used would still be ridiculous. They would just die rather quickly.
Again, the problem with this is the sheer power of that. Though I think I found a way to help you out. After going through all the ideas in my head.
The way to start out with it, without dying is this. Use Restoration - Aitan Magic. Make your familiar something small or something similar to this. Then use Creation Magic to magically build a body around it. Bam. Familiar that can be a puppet. Or you have the familiar go in a premade puppet. The familiar controls it so it'd move on it's own.
A way to do it as well would be using both Vruyk and Aitan Magic to make a contract with a spirit and have it possess a puppet. Again, this would take a ton of energy, but you could do it. Your energy reserves would just me lowered a lot from sustaining it. A LOT. Big spells would basically be impossible for you early. That SHOULD resolve the dilemma.
Both have a flaw. First Method's is the creature itself. By killing the familiar or hitting it, the puppet would be lost it's control for awhile. The Second's flaw is remaking the puppet. You'd spend a lot of energy remaking the puppet if it got destroyed or damaged. More specifically you'd spend energy giving energy to your spirit to reattach the pieces of the puppet. To go with this you'd probably need Gladys Magic to buff up the puppet so it doesn't get destroyed a lot. Which would have you depend entirely on the puppet for combat for the most part.
@Trouble: Looks good! :3
