Blizzard is a level 18 Frost mage ability that deals damage over 8 one second long ticks, each doing 1/8th the total damage, and slow all affected targets.


Calling down shards of freezing ice to batter and rend their enemies, Archmagi have been known to rout entire armies using this spell.[1] One of the Alliance’s most feared spells, Blizzard has become even more effective and deadly since its original inception during the First War. Summoning torrential storms from the frozen Mountains of Northeron, this potent spell calls down a fierce tempest of ice to assault the enemies of the Mage with a flurry of cold blades. Blizzard can be cast over large portions of the battlefield, making it an extremely powerful spell when facing legions of Orcish troops.[2]

The RPG Icon 16x36.png This section contains information from the Warcraft RPG which is considered non-canon.

This mage, wizard and sorcerer spell calls freezing sleet, snow and hailstones on foes. The cutting ice shards and hail pound down upon the caster’s enemies and foes, battering them and causing slashing, impact and cold damage.[3][4]


The 5 pc. bonus from the Netherwind Regalia set will increase the radius of the ground-target area by 25%, for a 10 yd radius.


  • [Shatter] increases the critical strike chance against frozen targets.

Tips and tactics

Most mages find this spell hard to cast fully in PvP. Because of the large number of debilitating procs on the spell, many targets will immediately begin seeking out and subsequently killing the mage casting Blizzard. However, in large or confusing battles, or from sufficient cover, it may be possible to cast the spell to its conclusion, doing damage and snaring the targets for the duration.

A single tick of damage from this spell is enough to reveal stealthed opponents and apply the snare; this can be useful in limited circumstances.

Farming and leveling with Blizzard

The Blizzard spell is a great tool to rapidly gain experience and to smash whole groups of mobs at once making it a powerful farming spell as well.

  • Ideal locations for this tactic have large numbers of mobs that have few or no ranged capability. These mobs will be caught in the snare and will stay packed together.
  • Maximize your effectiveness by attracting as many mobs as possible at once.
    • [Ice Lance] can help to gather mobs from a distance without exposing yourself (immediately, at least) to their melee attacks.
    • If the cooldown is acceptable, [Ice Block] can be used after gathering mobs, causing them to all catch up to you and surround your invulnerable body.
  • Use [Frost Nova] (especially if you're using the Ice Block method, above) to freeze mobs you have gathered and gain some distance from them before beginning your Blizzard casts.
  • If the mobs reach you before dying, use [Frost Nova] to regain distance. Alternatively, if they are low in health, a cast of [Cone of Cold] may finish them off.
