Most spells fall into two main categories; arcane and divine. All magic on Azeroth came from the kaldorei, both divine and later arcane. ( However, not all magic fits neatly into these two categories. Other magic types lurk outside or within arcane and divine, powerful and strange in their own rights. For example Priests have access to divine magic, while druids wield nature magic. ) ( One of the most sinister is fel magic. ) ( )
- Arcane - cast by arcanists
- Divine - cast by healers and experienced paladins
- Fel Magic - Often a darker form of Arcane.
- Rune Magic - Arcane in nature but accessed more naturally.
- Nature Magic (aka druidic magic () - Usually divine in nature, but also can be arcane. )
- Magic derived from the worship of ancestors, and by the power of ancestors is the ancestor domain. Several faiths believe in ancestral worship, including tauren, orcs, and tuskarr.
- The madness domain is magic often derived from chaotic and terrible sources such as the old gods. It grants power to certain nihilistic cults or crazed priests (. )
Spirits has some overlap with the Elements and the Ancestors domain. It can cover abilities dealing with ancestral spirits, voodoo spirits and elemental spirits/spirits of nature.

Speculation on explanations behind casting
Arcane, Runic, and Fel
Arcane and Runic magic involve manipulating ley lines, which were laid down by the titan Norgannon during the creation of the universe. By manipulating the energies of the ley lines, arcane and runic casters can manipulate the world around them, causing changes in the physical universe (. )
Similar to arcane and runic magic, Fel magic involves the caster's manipulating the physical world by making compacts with demons. Every manipulation of fel energies requires a small sacrifice of the caster's humanity to the demon world, having a similar effect as arcane magic, but without the burdensome study.
Hydromancy, Geomancy, Pyromancy, and Aeromancy are magical specializations that require the caster use his/her manipulation over supernatural forces (like manipulating ley lines or compacting with demons) to command the loyalty of the elements from within the Elemental Plane.
Necromancy is a similar specialization that allows fel (like the dreadlords) or arcane (Cult of the Damned) magicians to use their powers to call upon spirits from the afterlife and reanimate dead flesh as undead minions  (. )
Divine magic involves the blessings of a supernatural being.
The Holy Light of Creation grants supernatural healing and, in some cases, destructive powers to anyone who follows the strict discipline prescribed by its religious philosophy. More importantly, the user has to believe in the Light and that what they are doing is right.
The Forgotten Shadow provides similar powers to those people who follow its nihilistic religious doctrine. Troll witch doctors draw their abilities from the Loa gods, invoking their powers by enticing them with voodoo rituals (. Some of the abilities of a )druid are divine, drawing their power from the Night Elf goddess, Elune.
Nature magic involves drawing upon the spirits of the earth to invoke natural phenomenon.
Shamans draw upon the power of the elements, creating a personal relationship with each of the five elements (Fire, Water, Air, Earth, and Wilds) and asking for their assistance when it becomes necessary. This procedure is unlike the elemental practices of arcane or fel magicians, who use their manipulation over the physical universe to command the loyalty of elementals at their leisure (. )
Druidism draws its mastery over the natural world from the Emerald Dream, where the Spirit of the Wilds and the spirits of all living things in the universe reside. Unlike in shamanism, a druid makes a physical connection between his/her spirit and the spirits of the Dream, becoming literally a part of the natural world. This explains the way all druids appear to have foliage growing from them, and their ability to shape-shift, because their spirit has made itself one with all other living things (. )
There are arcane druids, who use supernatural forces to command a link between themselves and the Dream. Though this practice does require an advanced knowledge of the Emerald Dream, it does not necessitate the close connection and respect of the natural world that true druidism does (. )
