Maximum blades: Up to 10 blade stacks can be active at a time. Each stack has its own duration.
Hit interval: When the blade is first spawned, the skill will deal a hit after the hit interval duration (0.6 seconds with one blade).
Multiple casts: Blade Vortex can have multiple stacks, but it only has one skill effect, based on the original cast or trigger. This means effects that apply to entire casts of a skill must apply to the first cast to have an effect, and effects that only apply to additional blades will normally not affect Blade Vortex, such as less damage from Unleash SupportUnleash SupportSpell, Support Icon: q Level: (1-20) Cost & Reservation Multiplier: 150%Requires Level 38Supports spell skills, making their effect reoccur when cast.

Visual effect: Blade vortex's visual effect does not scale with Area of effect modifiers. Instead, to give a rough indication of radius, there are several versions of the knife effect, each rotating at a different radius. The skill will always try to have one knife using the largest-radius effect that's not larger than the actual radius of the skill, but that skill results in discrete visual changes where you need to reach a certain threshold before the next wider effect can be used. The full radius is always used mechanically.[2]

Calculating DPS
Blade Vortex's in-game tooltip DPS gives the average damage of one hit from one Blade Vortex instance, multiplied by casts per second. This value is misleading primarily because Blade Vortex can hit more than once over its duration, thus not cast speed must be used, but hits per second (rounds per second, spin rate), over the duration of the stacks.
Math and tables
Base spin rate of Blade Vortex is 600 ms. Blade Vortex hit more frequently with more stacks it has.
As gem says: 35% increased Hit Rate for each blade. So spin time is calculated as
Assuming spin rate increases for 35% for each stack, we have the following data:

Each stack of Blade Vortex increases hit damage with the following formula:
Where is per-stack damage increase factor.
Then we need just multiply hits per second with hit damage.
Assuming 35% more damage per stack, then using base hit damage as 1, we would expect the following per-hit damage increases:

Blade Vortex had its 'more spell damage' scaling modifier changed to 'more damage with hits for each blade', and separately 'more damage with ailments for each blade'.
Blade Vortex's "More Damage per Blade" modifier has been changed to apply only to spell damage instead of all damage types. This will remove a double-dipping effect that should not have been occurring.
Blade Vortex has been refactored. Instead of separate hits for each active blade, the blades now increase the frequency at which all enemies in the radius take damage, and the amount of damage they take. The skill now has a base hit frequency of 600ms and has 10% increased hit rate per active blade. Its damage has been reduced by 30% at all levels and it deals 30% more damage per active blade.
Extra Gore now doesn't trigger every time Blade Vortex hits.
Fixed a bug where some of the visual effects on Blade Vortex weren't being updated when swapping in and out support gems which modified the area of effect.
Fixed a bug where some of the effects of Blade Vortex weren't finishing their animations smoothly.
