Here's functions for base and rollback attack frames calculations.

So, no. You can't reach 3fpa. That "140 EIAS" (actually 141, flooring-ceailing magic) from the link you've posted effectively requires you to have 208 gear IAS and +35%IAS fanaticism.
Thb, 208 is already a lot more than you will have ever.

But let's put 18,446,744,073,709,551,615 IAS (max unsigned long long int) into your gear. for the science. Calculate. Bah. It's 185 EIAS and still 4fpa. The math.

The only way to get 3fpa, is to get an item with BoS, or something. Any SIAS buff will help, tbh. For example, 50% BoS + 35% fanaticism requires pitiful 293 IAS from the gear.

I am seeing this post only now, but you are confirming the numbers I ran here (https://forums.d2jsp.org/topic.php?t=88731105&f=148&o=0) with gel87.

With fana 15 (giving skill ias of 33) the new breakpoints are :

wsm -10 sias 33 eias 0 fpa 13 => ias -32
wsm -10 sias 33 eias 8 fpa 12 => ias -27
wsm -10 sias 33 eias 17 fpa 11 => ias -21
wsm -10 sias 33 eias 28 fpa 10 => ias -13
wsm -10 sias 33 eias 40 fpa 9 => ias -3
wsm -10 sias 33 eias 56 fpa 8 => ias 15
wsm -10 sias 33 eias 75 fpa 7 => ias 44
wsm -10 sias 33 eias 100 fpa 6 => ias 109
wsm -10 sias 33 eias 134 fpa 5 => ias 377
wsm 0 sias 33 eias 0 fpa 13 => ias -26
wsm 0 sias 33 eias 8 fpa 12 => ias -21
wsm 0 sias 33 eias 17 fpa 11 => ias -14
wsm 0 sias 33 eias 28 fpa 10 => ias -5
wsm 0 sias 33 eias 40 fpa 9 => ias 7
wsm 0 sias 33 eias 56 fpa 8 => ias 28
wsm 0 sias 33 eias 75 fpa 7 => ias 65
wsm 0 sias 33 eias 100 fpa 6 => ias 152
wsm 0 sias 33 eias 134 fpa 5 => ias 638
wsm 10 sias 33 eias 0 fpa 13 => ias -19
wsm 10 sias 33 eias 8 fpa 12 => ias -13
wsm 10 sias 33 eias 17 fpa 11 => ias -6
wsm 10 sias 33 eias 28 fpa 10 => ias 5
wsm 10 sias 33 eias 40 fpa 9 => ias 20
wsm 10 sias 33 eias 56 fpa 8 => ias 46
wsm 10 sias 33 eias 75 fpa 7 => ias 92
wsm 10 sias 33 eias 100 fpa 6 => ias 215
wsm 10 sias 33 eias 134 fpa 5 => ias 1480

Lines in bold are the new 6 fpa breakpoint. For GMB, you didn't reach the threshold because it is at about 215 IAS which is hard to reach, not doable with faith and lvl 15 fana only.

For shadow / diamond bow 155% gets you 6 fpa.

For mat bow I calculated 109% but apparently your testing shows 105 is enough ?


Very interesting also that crossbows now can shoot faster than 11 fpa... 7 fpa at 155% ias sounds good, even though diamond and shadow bows will get 6 fpa with this much ias.

I am trying to get the eias table for crossbows so I can calculate exactly how much ias is needed to reach the new breakpoints.




Strafe is the next question, how fast can it go now and at which breakpoints ?

console.log(strafe(20, 25, -10)); // highlord + faith merc // 4/2/7
console.log(strafe(70, 25, -10)); // 3/2/6
console.log(strafe(200, 25, -10)); // 2/2/5

So, basically, you can get 2fpa for strafe's rollback attacks with -10 bow, 15lvl fanaticism and +20% IAS from gear. +70% IAS from gear will give something like 3/2/2/2/6 per strafe. 15 frames for 20 arrows. Not bad, but multishot is still better ( with ~9 frames per 21+ arrows ).

but the strength of crossbows is its faster strafe : ias

can you calculate the strafe fpa for -60 wsm chu/demon xbow and 160-193% ias on gear?

Some updates. 15 level fanaticism gives 33% buff, not 25%.

console.log(strafe(0, 33, -10)); // 4/3/7
console.log(strafe(20, 33, -10)); // 4/2/6
console.log(strafe(44, 33, -10)); // 3/2/5

So, basically, you can get 2fpa for strafe's rollback attacks with -10 bow, 15lvl fanaticism and +20% IAS from gear. +44% IAS from gear will give something like 3/2/2/2/5 per strafe. 14 frames for 20 arrows. Not bad, but multishot is still better ( with ~7 frames per 21+ arrows ).

Base attack ( like multishot ):
console.log( baseAF(20, 40, 33, -60) ); // 8-frame with cho-ko-nu
console.log( baseAF(14, 15, 33, -10) ); // 8-frame with mat-bow
console.log( baseAF(14, 44, 33, -10) ); // 7-frame with mat-bow
console.log( baseAF(14, 109, 33, -10) ); // 6-frame with mat-bow

The same 15lvl fanaticism + 44IAS from gear will grant you 7fpa multishot. To break this you need to wear 109+ IAS ( still possible: gloves+10, highlord+20, jeweled andy face +35, treachery +45. Something like the Ice RW allows to swap andy face with any other jeweled headpiece ).

In result, Amas won't get crazy benefits from the bug. Only kicksins really got buffed because of theirs BoS.

have you still not calculated -60 wsm? or am i missing something here

its the most extreme case at least for strafe?

+ for pvp you're not using a mercenary.. -- with a zon wielding the faith its still getting a massive buff that cant be understated.. a sin won't have access to fanat unless they have their merc

-60 wsm on the old table is hitting 3fpa strafe with only 8 ias.. really curious what your fpa would be with 193 ias.. attainable ias by normal means

If you say so, then I guess, I need frame-data for strafe with xbows. Using bow's frame-data and just changing weapon speed parameter will bring us to:
console.log(strafe(0, 33, -60)); // 3/2/5
console.log(strafe(38, 33, -60)); // 3/2/4
console.log(strafe(63, 33, -60)); // 2/2/4
console.log(strafe(259, 33, -60)); // 2/2/3

So, with 15lvl fanaticism only it should be 3/2/2/2/5 already: ~14 frames for 20 arrows. 40IAS removes 1 frame from it. 63IAS removes another one: 12 frames for 20 arrows. And that's it. I consider 259% gear IAS as unreachable.
I wrote ~14frames, because there is fluctuation in chained strafe animations. Sometimes it will eat 1 frame, sometimes it will add 1.

Attention: I calculate strafe as combination of base attacks (windup and finishin) and rollback attacks (in the middle). Only in this way parameters are matching to AmazonBazin frame-data. In comparison, dTalon uses singe base attack, the rest are rollback ones.

hmmm but i can see a noticable difference in attack rate on strafe with going from 143 to 123.. there must be something in between there? hmm still a bit confusing

the bow frame data isnt the same clearly as the table is completely uh staggered or just different.. this cant be right

For pvp it isn't so funny, because you must wield Faith by yourself to get the fanaticism aura. And so on, you can't get guided-frost-nova-katyasha in your chi-ko-nu.

P.S. I don't have pc for d2, can't test on the hero-editor how xbows really work with strafe. Would be nice to see somebody tests (ice rw chi-ko-nu with 63 overall IAS from gear).

i have a demon faith on live and can confirm the above calculation is wrong?

i am definitely seeing a difference in attack rate.. or maybe its just the startup im noticing take effect?

cant be becasue im seeing a difference from 123 and 143% total ias..

Fanat 15 - 33% treachery 45, 45 helmet, 20 glove.. then just removing the one piece there is a noticable difference..
