The breakpoints are fairly simple. If you are above a given APS in the table, your WW tics for the number of times listed, over the full 6s duration. Also note that your in game displayed APS only shows 2 decimal places while the game uses the actual APS. If you want to be sure you are at the appropriate breakpoint, it's best to either calculate your APS manually, or use a reference table like the one found in the link below.

Manual APS calculation formula

`APS = (Base Weapon Speed * (1+Weapon IAS/100)+Bonus APS)*(1+sum(IAS)/100)`

Base Weapon Speed

Dagger: 1.5

Wand/Sword: 1.4

Bonus APS includes 0.03 for enchantress and 0.21 to 0.25 from chanto MH.

sum(IAS) doesn't include weapon IAS but does include 10% from the IAS slow time bubble if applicable

And for those curious enough to want to know the actual formula used to obtain the values in the table, here it is, again courtesy of Voltara:

`frames_per_attack = floor(30 / attacks_per_second)`

tick_rate = ceil(360 / frames_per_attack)

For more information about the formula and how it applies to other, similar skills, see http://us.battle.net/d3/en/forum/topic/8704740408#6

Thread with IAS/APS breakpoint reference table that shows how much IAS you need from gear to reach some of the breakpoints for a given weapon.

another method for calculating ur aps is

take ur weapon atk spd

and multiply it by the ias you have on ur gear

ie for me it is currently 1.65 x 1.66 (currently have 66ias on gear)

like i herd having 2.5 aps with 50+ CC is like having 2.73 aps.

Added formula to calculate APS manually for those who prefer that to a reference table.

like i herd having 2.5 aps with 50+ CC is like having 2.73 aps.

I think the rough estimate is 6-8 CC is like adding 1 breakpoint. You can try playing with steves CMWW dps simulator if you want a better idea. I don't have the link for it but you should be able to find it with a search. Keep in mind those results should still just be taken as an approximation, but it should still be a better approximation than me trying to remember a post I read a while back.

For people interested in the topic, it's also worth mentioning that a good deal of what we know about skill breakpoints comes from the work done by:

**Nubtro**- I'm not 100% sure, but I think Nubtro discovered the first skill breakpoint. This was for the Barbarian Skill (Run Like the Wind) around last July: http://us.battle.net/d3/en/forum/topic/6037344497 . He's also been at the forefront at analyzing the breakpoints for most barb skills, but he's looked at a few other skills for other classes including wizard: http://us.battle.net/d3/en/forum/topic/8568958682?page=2#39 .

**European Gang (plus Shandlar and apo)**- Also if I remember correctly, a lot of the initial discussion of breakpoints for Wicked Wind were discussed in this thread: http://eu.battle.net/d3/en/forum/topic/5208511084 . And fortunately a lot of that the breakpoint research is translatable over to other skills. The speed coefficients for wizard spells listed in this thread can be used to estimate the breakpoints for our other wizard skills:

base_frames_per_attack = 60 / speed coefficient

actual_frames_per_attack = floor(base_frames_per_attack x attacks_per_second])

tick_rate = ceil(360 / actual_frames_per_attack)

P.S. Note that the base_frames_per_attack is 30 for WW (like Loroese's formula above), because WW has a speed coefficient of 2

like i herd having 2.5 aps with 50+ CC is like having 2.73 aps.

I think the rough estimate is 6-8 CC is like adding 1 breakpoint. You can try playing with steves CMWW dps simulator if you want a better idea. I don't have the link for it but you should be able to find it with a search. Keep in mind those results should still just be taken as an approximation, but it should still be a better approximation than me trying to remember a post I read a while back.

To put it in a simple but not completely accurate way,

1 bp higher basically gives u 10% more ticks on ww. So in order to make up the 10% difference, ur crit chance need to be 10% higher, which usually translates into 5-6.

Then on top of that, to make up the increase in attack speed on other non-ww skills, u need a little more than 10% crit chance increase, so in general 12-14% crit chance increase should make up for the breakpoint, which translates into 6-8 crit chance in most cases.

And that's a falacious assumption, as casting more twisters still means more overall ticks. The number of twisters at full wind up is: 6s x (Attack Speed - Frost Nova Casts Per Second), and usually people suggest the number of frost nova casts per second is 0.95aps (which is required for permafreeze). And arguably casting more twisters is potentially the most dominant component of gaining attack speed, even more than the breakpoint itself.

For example, if we compare 2.73aps to 2.51aps, we see the following:

WW Tick Efficiency of 2.51aps = 100* (33 Ticks / 36 Ticks) = 91.67% as efficient as 2.73aps breakpoint.

WW Casting Efficiency of 2.51aps = 100*([2.51-0.95]/[2.73-0.95]) = 87.6404% as efficient as 2.51aps

So for trying to make up for lost attack speed, you need to account for both components. And the reduced casting efficiency contributes potentially even a larger portion than the breakpoint itself.

And to make matters worse, the tricky party in all this is how our Frost Nova casts impair us! I assumed 0.95 casts per second, which is what is required for permafreeze on elites; however, that most certainly is not what we're casting in practice. It's a complicated feedback loop too, because if you have more WW crits (either from more twisters, more ticks, or more cc) then Frost Nova takes up more of our actions per second, which in turn reduces the number of twisters you have. So yeah it's a mess. Thus, I think for most people it's best to use Steve's CM/WW wiz simulator (d3cmww.com ), since it's sadly a very complicated system.

I couldn't agree more with what you said. The simple calculation I posted is to give players an rough estimate on how much crit chance u need to make up for the breakpoint difference.

BTW: I believe 1.05 sec interval is the threshold for theoretical permafreeze of elites.

But the reason I brought up what I did is that while Loroese and you are right in saying you need about 7%cc for the breakpoint itself, it's potentially misleading to someone reading it. The breakpoint ITSELF may be worth 6-8cc, but the difference of someone at 2.51aps vs 2.73 aps requires a lot more cc than just 6-8cc to make up not only for the breakpoint, but the reduced number of twisters.

Using the D3CMWW.com simulator, I estimate that a wizard with 2.5aps per second requires 61cc just to have the same number of CM procs as a wizard with 50%cc and 2.73aps. Thus, it's more like 11cc to make up for everything. Now in contrast a wizard with 2.72aps (just short of the breakpoint), requires only 7% more cc to equal someone at 2.73aps and 50%cc. This is what I believe both Loroese and you are discussing. But it's potentially misleading, since players cannot assume that being at 2.51aps and +7%cc will cover the complete difference. It sadly won't... and that's because they need to account for the reduced number of twisters at full wind up.

Thanks!
