You can't really create souls, I'd say. But Life magic will still work!
Thing is, magic in the book can do everything that this system can do, except healing. So all of the other uses of Life magic - encouraging plant growth, sensing living things, creating constructs and a few others - they can all be done. You just can't fix a broken bone. So you can legitimately shove someone's body full of magic and turn them into the Hulk! I've been saying that Life magic won't exist because none of them will - the book doesn't have the eight elements. In the book, healers (Not people with the White Circuit, just normal healers) use magic to supercharge medicines. They tend to be apothecaries and skilled at surgical procedures and such, along with using fine control of magic to either increase the potency of medicines or assist in surgery. (You want a clean cut? A razor-fine line of magical energy will do that for ya!)
For the game, I just cut out a lot of the menial work and said "it's all magic", mostly 'cause I don't want to describe hours of surgical procedures.
Yes, I will let you learn how to make healing potions. If you're a good boy and study hard.
The book's laws aren't as scientifically rigid as they are for this game - magic is more, well, magical. I'm simply using science to curtail a few of your more insane ideas. If you wanted, you could probably just pour the pure essence of magic itself into something and see what happens. You just don't get any elemental experience from that... Honestly, I'm not entirely sure what that'd look like.
For regarding the golem, Life magic would still be the basis, along with wind and fire - since Wind+Fire makes lightning, which you need for circuitry and control... if you're going to make replicas of nerves. Or maybe just build from your wisp spell? That thing is already semi-autonomous as it is.
