The trailer illustrating the new class showed actual gameplay demonstrating the Wizard's spells and abilities, some of which hearken back to the Sorceress in Diablo 2. Attacks such as Meteor and Chain Lightning seem to be returning, and several new spells were seen, including one invoking a spherical shield that seems to alter the flow of time within it, allowing the Wizard to dodge projectiles and approaching enemies with ease. Another spell sends tornadoes storming through the room. Here's Blizzard description of the class from their press release: "The wizard is a wielder of the elements and a master manipulator of time, who combats the hordes of the Burning Hells by launching environment-shattering lightning bolts, channeling explosive arcane energies, and creating pockets of space outside of the normal flow of time."
Blizzcon is officially underway today, starting with a presentation showcasing the Worldwide Invitational tournament held earlier this year. A company spokesman went on to talk about the tournaments being held for World of Warcraft 3v3 Arena, Warcraft 3, and Starcraft 2, followed by word that Starcraft 2 was not yet ready for beta, but that Blizzcon attendees would be included in the first round of testers when the beta program starts. The big news of the presentation, though, was the unveiling of the Wizard class — the third such class to be announced, along with the previously mentioned Barbarian and Witch Doctor. Read on for some more details.
