Blade Flurry

Blade Flurry is a channeling melee attack. While channeling, Blade Flurry repeatedly attacks a random enemy in front of the player, also damaging enemies nearby the original target. When released, it will unleash an extra number of attacks equal to the stage reached.

Skill functions and interactions

• Stages: Each attack, while channeling, applies a single stage that grants 20% more damage, up to 120% more damage total at 6th stage. Each stage will also add an extra attack to the release of Blade Flurry.

• Dual wielding: The skill alternates between the main hand and the offhand for each hit.

• Area of effect: Modifiers to area, such as Concentrated Effect Support and Increased Area of Effect Support , affect both the radius of the main hit and the radius of the explosion caused by it.

• Trigger supports: While both Cast On Critical Strike Support and Cast while Channelling Support can support Blade Flurry independently, they won't work in tandem; neither will trigger.

• Multistrike Support: Blade Flurry (and all channelled skills) cannot be supported by Multistrike.

DPS Calculation

Blade Flurry's tooltip DPS is not accurate, because it shows Average Damage (ignoring Attack Speed) and doesn't account for stage bonus. Here is how to calculate the actual DPS:

where Base is the base damage given by gem level, and StageMult ranges from 1.1 to 1.85 (see table in Derivation) depending on which stage level was reached before releasing. This formula also assumes the player's return strike(s) can hit an enemy; remove the 2 in the middle to approximate what happens when the return strikes don't hit an enemy.

For example, at gem level 20, with "perfect channeling," as of patch 3.14:

or 266% weapon damage per second. Note that the DPS will be slightly lower in practice because players cannot reach perfect channeling, only get very close.
