In case of any confusion over what magic element does what I am making this topic to do just what the title says, clearly lay out what each magical element does.
Earth- Control over rocks and ground, this element manipulates the soil, rocks and minerals on earth.
Water- Water magic manipulates the water around a mage; the water can be pulled from air, plants, or natural sources such as a lake or river.
Fire- Fire controls heat (Both hot and cold) and flame. It can start fires from nothing or suck all the heat out of an area.
Air- Air controls all non-water gasses.
Lightning- Lightning is the creation and manipulation of energy. This includes electricity, light, sound, and gravity listed in order of difficulty, as heat is considered fire it is not included.
Life- Life is magic revolving around the natural world, it includes manipulating plants, and at higher levels animals.
Death- Death revolves around raising the dead and the instant killing of lesser creatures (plants, animals) it is used to create famine and draught and can cast physical de-buff spells.
Holy- Holy magic is blessings and healing spells.
Unholy-Unholy magic is composed of curses and summoning demons.
Void- Void magics focus on bringing a small piece of the void, the source of all magic, into our world. It is usually used in order to cancel out other magic, though masters are able to bring a part of the void into themselves greatly increasing their magical and physical abilities almost to the point of being on par with magical beings such as demons and elementals.
