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.

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

$\color[RGB]{163,141,109} Spin Time = {Base Spin Time \over (1 + Spin Time Reduction \times Stacks Count) }$

$\color[RGB]{163,141,109} Rounds Per Second = {1 \over Spin Time} = { ( 1 + Spin Time Reduction \times Stacks Count) \over Base Spin Time}$

Assuming spin rate increases for 35% for each stack, we have the following data:

Stacks	Hit Rate (ms)	Hits Per Second
0	600	1.667
1	444	2.250
2	353	2.833
3	293	3.417
4	250	4.000
5	218	4.583
6	194	5.167
7	174	5.750
8	158	6.333
9	145	6.917
10	133	7.500

Each stack of Blade Vortex increases hit damage with the following formula:

$\color[RGB]{163,141,109} Hit Damage = {Base Hit Damage \times { (1 + F \times Stacks Count ) } }$

Where ${\textstyle \color[RGB]{163,141,109} F }$ is per-stack damage increase factor.

Then we need just multiply hits per second with hit damage.

$\color[RGB]{163,141,109} Damage Per Second Multiplier = {Hit Damage \times Rounds Per Second }$

Assuming 35% more damage per stack, then using base hit damage as 1, we would expect the following per-hit damage increases:

Stacks	Damage Per Hit	Effective DPS Multiplier
0	1.00	1.667
1	1.35	3.04
2	1.70	4.82
3	2.05	7.00
4	2.40	9.60
5	2.75	12.60
6	3.10	16.02
7	3.45	19.84
8	3.80	24.07
9	4.15	28.70
10	4.50	33.75

Finally, to obtain sustained DPS from tooltip use the following formula:

$\color[RGB]{163,141,109} Sustained DPS = { { Damage Per Second Multipier \times Tooltip DPS } \over Casts Per Second}$

or in expanded form

$\color[RGB]{163,141,109} Sustained DPS = { { { ( 1 + {Per Stack Damage Increase Factor \times Stacks Count} ) \times ( 1 + {Spin Time Reduction \times Stacks Count} ) } \times Tooltip DPS} \over ( {Casts Per Second \times Base Spin Time} ) }$
