Studies for a Wizard, in how to increase the mana-efficiency of her spells.

Skill Design[edit]

It looks like a Wizard will be able to greatly customize his or her spells in D3, with passive skills that cut mana cost, increase casting speed, and boost individual damage types. It's not yet known how much equipment will overlap with these abilities; a spell to boost casting speed wouldn't be much good in D2, with so many items that could convey the same bonus.
