Wizard (character class)

The Wizard is a type of magical character class in certain role-playing games, including role-playing video games. Wizards are considered to be spellcasters who wield powerful spells, but are often physically weak as a trade-off. Wizards are commonly confused with similar offensive spellcasting classes such as the Warlock and the Necromancer. However, a Wizard's power is based on the arcane and a Warlock or Necromancer's power is based on darkness or death. Wizards are primarily based on wizards from assorted fantasy literature. Other terms used to describe the classification include Mage, Magician, and Magic User.

The Dungeons & Dragons pen-and-paper franchise has three base character classes, with access to "arcane magic", that could be considered wizards:

The wizard is a "genius student" of arcane magic, who has studied the subject for years. He practices until he is able to command magic with ease. The wizard must prepare spells daily. They are normally called 'magic-users'.

The sorcerer is a "natural prodigy" arcanist, who usually claims dragon or fey ancestry as the source of his magical power. The sorcerer knows a limited number of spells, but does not need to prepare the spells daily. The sorcerer is able to cast more spells per day than a wizard of a comparable level.

The Warlock is a "darkened soul" arcanist, who creates "Pacts" with powerful creatures to harnessing their innate magical gift, and perform spell-like feats and abilities. Since they are not users of true spells in the traditional sense, they can use their invocations while wearing armor.
