[[File:Arcanepower.gif|frame|The main difference between Arcane Power and Mana is that the pool for Arcane Power bulbis a fixed value.The default value is 100 but can be increased or decreased by [[Wizard skills]]([[Energy Armor]]) and [[Wizard Passives]] ([[Astral Presence]]) by a small amount.

The main difference between ===Arcane Power Skills and Mana is that the pool for Arcane Power does not increase. It's always just 100, and the relevant Passives===Several [[Wizard skills]] and [[Wizard traitsPassives]] make for faster regeneration are devoted to boosting (or lower cost per skill, rather than increasing the total pool. This may be its undoing, as the developers aren't entirely happy with how the resource functions, and as of October 2010 they were still considering dumping it and returning the Wizard to mana.

<blue>Jay Wilson: "Well for the Wizard we want to enforce the fact that she’s a glass cannon. I don’t think it’s fun to ever run out of mana. I’m not really interested in an extended resource for her. For the Witch Doctor we’re okay with mana, since he’s got some pretty good skills to recover mana that also double as attacks. And he’s not defenseless when he’s out of mana. He's got pets and ways to attack with them that aren’t mana intensive. For him that makes mana fairly interesting. "

For the wizardArcane Power sounds like it enables this by giving a resource pool that's never really empty, when she’s out of mana she just dies. And that’s not fun. So but that will run down if anythingbig, we want powerful skills are used rapidly. Thus wizards in Diablo III should always be able to encourage how she plays. So she’s the kind cast some of character that blasts first and asks questions later. Very vulnerable. So we want to implement a system that makes her more blastytheir lower level spells, but even will have to be more vulnerable. We want to make that a choice for selective with using the player. "Do I want to make myself bigger, more vulnerable in exchange for being more blasty." And that’s a cool gameplay pull thereAP-expensive spells. </blue>

Right now, Arcane Power does not scale, but that will run down if and that’s the big, powerful skills are used rapidlydifference between the Wizard’s resource and the Witch Doctor‘s mana; the Wizard’s resource does not scale up over time. Otherwise they’re very similar. Thus wizards in Diablo III should always be able If we change that about mana the Wizard might just go to cast some of their lower level spells, but will have mana and we’d change the Witch Doctor’s to be more selective with using the bigger, more AP-expensive spellssomething new."</blue>

<blue>Jay Wilson: "For the Wizard, we could not get a version of Instability that we liked. The last version involved buff and debuff that would hit the wizard whenever she went unstable. And it was a pretty severe buff. It doubled all her damage taken while increasing her critical hit damage. And it just didn’t affect how people played. They didn’t notice it, and when they did it didn’t change what they were doing. That’s not the point of a resource. It needs to be managed to change the way that you play. "

"So now it’s called [[Arcane Power]] and it’s not dissimilar to mana, in a lot of ways. It regenerates very quickly, but it doesn’t grow over time. It’s a flat amount. A lot of passive skills that enhance it."</blue>
