Notes

Flurry increases your attack speed for the next 3 swings after you land a critical strike. It is useful for high crit builds as the constant swings combined with a high rate of crits will allow Flurry to be maintained for a large portion of a fight, resulting in significantly increased DPS.

If you do not use up all 3 swings of Flurry within 12 seconds, it will fade. This fairly long duration means that if you end a fight with a crit, you can easily start fighting a nearby mob and use your Flurry on it. Warrior abilities such as Mortal Strike or Heroic Strike will not use charges of Flurry, as it only speeds up 'normal' swings. There is a rumor, that if your weapons have the exact same attack speed, you will gain 1 extra attack due to your weapon will attack at the same time.

Flurry will consume charges regardless of whether your attack hits, misses, or is dodged/parried/blocked. Critting during a Flurry will result in giving you a fresh set of 3 charges.

Past changes

In Patch 2.4.0, Flurry was fixed so that it can now proc from offhand weapon strikes.
