Diablo III Class Resource Systems

The official Diablo III community website is sporting a new class resource systems page that breaks down the various sources each class will tap into for their abilities. The Barbarian utilizes Fury, the Demon Hunter uses Hatred and Discipline, the Monk uses Spirit, the Witch Doctor uses Mana, and the Wizard uses Arcane Power:

Similar to the witch doctor, the wizard is a powerful magic user who obliterates evildoers, often from a distance. Unlike the witch doctor, however, the wizard relies less on summoned creatures, and doesn’t perform wicked spells or use Mana. The wizard instead draws from Arcane Power to use spells of varying disciplines. Arcane Power is a fast regenerating resource and allows you to perform spells such as Ray of Frost, which projects a beam of ice that blasts the first enemy it hits with repeated Cold damage, also slowing movement and attack speed. Arcane Power fuels capable defensive spells like Energy Armor, which increases your Defense for a short period of time at the cost of lowered maximum Arcane Power for its duration. Other spells can be used with Arcane Power to allow the wizard to escape, or stay out of the grasp of the damned. For instance, Teleport lets you jump through the ether to a selected location, while Slow Time invokes a bubble of warped time and space, slowing the movement and attack speed of enemies and their projectiles. Ever attuned to the Arcane forces of their realm, wizards dominate opponents with deadly damaging spells, an array of ethereal magic to keep villains at a safe distance, and elegant defenses to mystically mitigate incoming damage.
