Life magic is unique in that it doesn't have a pure form, the magician needing to manifest it through another element. It's most common use is for medicinal purposes, but it can also be used for: translators to cross language barriages, communication with animals/plants, and farming. Life magic can also be used in necromancy, bringing life to the dead, and animation, bringing life to the inanimate.
There are two types of necromatic spells, reanimation and resurrection. Reanimation does not bring someone back from the dead, their living corpse a mindless servant for the magician. Resurrection does bring the dead back to life, but how much of the person remained depends on how decomposed the body is. Resurrecting someone within hours of their death will result in minor memory loss, but resurrecting a half-decayed corpse will not only wipe the magician of nearly all their energy but also bring the person back with little to no memory of who they were before.
Animation spells are far more complicated, requiring nearly all a magician's energy and regular recasting. The more the object being animated resembles a human or animal, the more intelligent the construct is. All successful constructs can follow commands, but smarter ones can act on their own will when not under order.
