A spellcaster refers to a creature capable of casting magic spells. The term is most often used in fantasy books and role-playing games.

The term groups all kind of fictional magic users:

• Arcane casters: Sorcerers, wizards, witches, warlocks, illusionists, etc. This type of magic is based on heavy study and formulas.
• Shamanic casters: Shamans, Druids, etc. This type of casters get their power from nature, or borrow power from magical devices.
• Divine casters: Clerics, Priestesses. This type of casters get their powers from their gods or goddesses. They are often limited by their gods (A water god may not provide fire spells).
