[Alexstrasza's Fury] (Talent) - Causes Dragon's Breath to always critically strike, increases its critical damage by 50%, and allows it to contribute to [Hot Streak].
Despite the tooltip, damage over time effects will not break the disorient effect. However, certain DoTs that also deal direct damage (such as the flare up effect [Conflagration]) will break the disorient effect.
Tips and tricks
The disorient effect makes this spell not only useful to kite an opponent, but also to interrupt spell casting. Although there is no spell lockout such as with [Counterspell], interrupting a spell for 4 seconds is sometimes all you need.
This spell previously shared a cooldown with [Cone of Cold]: using either spell would set the cooldown of the other. Casting Dragon's Breath would set the Cone of Cold cooldown to 20 seconds, and casting Cone of Cold would set the Dragon's Breath cooldown to 10 seconds.
