Changes

Magic Missile's effectiveness is increased by a variety of spells, the most noteworthy of which is Improved Magic Missile, which increases both the damage and number of missiles released on a cast. The range and spread of higher levels of Magic Missile is reminiscent of the DII Necromancer's Teeth. When an enemy dies at the hands of an Arcane spell, a purple glow is left on the corpses.

===Arcane Power===

* '''Description:''' Increases all arcane damage.

*'''Max Rank:''' 15

This mastery boosts the arcane spell damages by a much higher % than similar masteries for other types of damage, and it's unclear why. Possibilities include: arcane spells generally do less damage, their critical hit bonus might be less useful, or the spell just might be overpowered in this early, still-under-testing build.

===Efficient Magics===

* Passive Skill

*''' Max Rank:''' 15

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.

* Active Skill

*'''Mana cost:''' 12 per sec.

In the Blizzcon demo build, this spell wasn't very useful against large enemies, but was devastating against smaller enemies, especially ranged attackers such as [[Skeletal Archer]]s. The disintegrate ray hits anything on the screen more or less instantaneously, so nothing is out of reach and there's no delay between clicking the mouse and hitting the enemy with the spell. This one will surely be nerfed somewhat before the final game.

===Wave of Force===

This would presumably stack with other passives that increase the damage and critical hit % of individual spell types, or all spells in general.

===Arcane Speed===

Arcane spell damage seems to be limited by a cooldown time on most of the spells, hence this spell.

In one of the BlizzCon 2008 panels, Teleport was demonstrated with a striking [[skill rune]] socketed in it, and the spell added damage to all monsters in the area, each time the Wizard teleported. Socketing in a multi strike skill rune will instead cause the wizard to split into images of herself when teleporting, making the skill useful to distract monsters.

===Greater Mana===

A straight forward skill that increases your mana, useful throughout the game, especially at early levels.

===Mana Burst===

* Passive Skill

Another creative spell. This one basically lets the Wizard deal substantial extra damage, but with just one spell, once in a while. A wizard who invested in this spell woulc have to modify her play style considerably; trying to use spells sparingly to remain full of mana, in order to score the huge damage hit possible with points in this skill.
