Talent improvement

Blast Wave deals fire damage, and thus gains the benefit of the talents Impact, Ignite, Burning Soul, Master of Elements, Critical Mass, Fire Power, and Precision.

As with all mage spells capable of critical hits Arcane Instability, Spell Power, Molten Fury, Playing with Fire and Shatter can increase the effective damage output of this spell.


There is some confusion over Blast Wave's daze effect. The daze itself (which is also called 'Blast Wave') is classified as being in the physical school, however, it is different from other daze effects in that it is an effect of a magic spell. Any ability that removes movement impairing effects or remove's harmful spell effects thus also removes the daze from Blast Wave. This includes, but is not limited to, a paladin's Blessing of Freedom, a rogue's Cloak of Shadows, or any immunity granting effects such as Ice Block or Divine Shield. Similarly, the daze effect from Blast Wave does not dismount players. There are reports, however, of players being dismounted by blast wave due to the knock back effect being added in patch 3.0.

Tips and tactics

This spell is cast in the same situations as Arcane Explosion, with the added benefit of snaring everything it hits, and knocking them back a few yards.

Between Blast Wave, Frost Nova, Cone of Cold, Blink, Cold Armors, and Frostbolt, a mage is a slippery target to catch.

This spell adds another spell to both the mage's area damage and crowd control lists. It deals excellent damage, and the daze allows a mage to run clear and start another spell before the targets come back to full speed. The knockback is an excellent way to put space between the mage and melee attackers, especially in PvP.
