Improved Blizzard (mage talent)

Improved Blizzard is a Mage talent that adds a chill effect to the Blizzard spell, which slows opponent movement speed for one and a half seconds. This talent is used primarily for aoe, and can be quite useful wherever one wishes to snare a large number of enemies all at once.

At max rank, Blizzard will be one of the mage's strongest snare spells, matching the 50% of Cone of Cold. These snare effects do not stack; if Cone of Cold is in effect (with more than 1.5 sec left), the snare from Blizzard will not overwrite it.

Improved Blizzard makes the Blizzard spell an effective snare, but at a large mana cost. This chill can proc Frostbite, Brain Freeze and, for most important, Fingers of Frost. Since the snare is reapplied every time it hits (which is often) Fingers of Frost will proc often, making Frost mage AoE devastrating when coupled with Shatter.
