Blade Vortex (often referred to as BV) is a spell that creates an ethereal blade that spins around the caster that deals physical damage, each blade lasting for the minimum duration of 5 seconds.
Skill functions and interactions
Blade Vortex's base damage is boosted by Physical Damage, Spell Damage, Area Damage, and Damage.

Poison: As Blade Vortex deals physical damage, it can easily scale poison damage.
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. [1]

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: 10% increased Hit Rate for each blade. So spin time is calculated as
Assuming spin rate increases for 10% for each stack, we have the following data:
Stacks | Spin time, ms | Rounds per second |
---|---|---|
0 | 600 | 1.667 |
1 | 545 | 1.833 |
2 | 500 | 2.000 |
3 | 462 | 2.167 |
4 | 429 | 2.333 |
5 | 400 | 2.500 |
6 | 375 | 2.667 |
7 | 353 | 2.833 |
8 | 333 | 3.000 |
9 | 316 | 3.167 |
10 | 300 | 3.333 |
11 | 286 | 3.500 |
12 | 273 | 3.667 |
13 | 261 | 3.833 |
14 | 250 | 4.000 |
15 | 240 | 4.167 |
16 | 231 | 4.333 |
17 | 222 | 4.500 |
18 | 214 | 4.667 |
19 | 207 | 4.833 |
20 | 200 | 5.000 |
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 30% damage increase per stack, then using base hit damage as 1, we would expect the following per-hit damage increases:
Stacks | Damage per hit | Damage per second multiplier |
---|---|---|
0 | 1.0 | 1.667 |
1 | 1.3 | 2.383 |
2 | 1.6 | 3.200 |
3 | 1.9 | 4.117 |
