Healing is the ability to heal wounds and diseases.
Healing at lower levels can cure cuts and lower fevers. At higher levels, healing magic can mend broken bones and cure infectious diseases.
There are some things that healing magic cannot do – it cannot re-grow lost limbs, though a severed limb may be reattached by a sufficiently skilled mage if it is done immediately. It cannot cure genetic disorders, such as nearsightedness or dwarfism. Healing magic also cannot hold death off forever – a body which is failing will, eventually, fail, and healing magic can only soften the way. (See: Average Lifespans)
