Arcane Power

Arcane Power is the resource used by for the Wizard for casting her spells. It was revealed in an interview with Jay Wilson after the Artisan reveal in GamesCom 2010.

Background

Arcane Power works very much alike to the Rogue's Energy from World of Warcraft, where there is a preset amount of resource that recovers very fast. It allows the wizard to effectively never run out of the Arcane Power, therefore she can use spells at anytime without hindrance. It cannot be increased statistically, but various skills in the Skill Trees can empower it.

Mana was the standard resource that people thought the Wizard would use for using her spells, it even had skills in the various trees that empowered it in various ways. It was later replaced with Instability, that would allow the wizard to never run out of resource and to her provide with a choice, which is to be safer or to hit harder. This proved too much, as when wizard became unstable she would take double damage from all sources and only had an increased critical chance to show for it. It has since been replaced with arcane Power.
