Instability = gone. Arcane Power! Good new Jay Wilson interview from Gamescom, and here's what he said about the Wizard's resource system. 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 didnâ€™t affect how people played. They didnâ€™t notice it, and when they did it didnâ€™t change what they were doing. Thatâ€™s not the point of a resource. It needs to be managed to change the way that you play. So now itâ€™s called Arcane Power and itâ€™s not dissimilar to mana, in a lot of ways. It regenerates very quickly, but it doesnâ€™t grow over time. Itâ€™s a flat amount. A lot of passive skills that enhance it. So, all of our past discussions on what sorts of buffs/debuffs would make Insta work are... Not too much detail about the resource from this new quote (which is a rough transcript I did very quickly; if someone wants to get his precise wording, that would be great). So it's a pool that doesn't increase from stats, but that regens very quickly, and has a lot of skills that increase the regen. Why would you need multiple skills to increase the regen? Warmth was plenty in D2. I'd guess the regen options aren't just from time. Probably you can tie regen to kills registered, critical hits scored, and other stuff? Thoughts?
