Poet's Pen not casting 2nd attack when getting fractionally close to 4.00 APS

EDIT5: https://www.youtube.com/watch?v=iSOnjJ9EZ_I&feature=youtu.be This video debunks a couple of theories as to why this is happening, but should be viewed after my first video (below)
------------------------------------------------------------------------------------------


Dual Wielding

3.66 APS will cast on every attack when holding down Attack

3.82 APS only casts every other attackwhen holding down Attack

These are the only break points I can reasonably test. I was trying to get as close 3.99 APS as possible, for maximum efficiency. Toying with gear to do so. I noticed a difference once reaching close to that 3.99 though.

As above, if I have 3.66 APS (per tooltip), I will cast the socketed spells in both wands, but once reaching 3.82 APS (per tooltip), I will ONLY CAST every other attack, meaning it breaches the 250MS breakpoint, although that is not the case.

So somewhere between 3.66 and 3.82 APS, the item is thinking I'm attacking faster than 250MS per attack. Can I get some acknowledgment of this?

Thank you

Edit: If relevant, Attack Speed modifiers I am using with Dual Wield Poet's Pens (12% AS and 11% AS on my Pens):
* Lightning Golem (Lvl 19)
* Frenzy Gem, no quality (with Frenzy Charges)
* Elder Gloves: Socketed Gems are Supported by Level 16 Faster Attacks, 8% inc AS.
* 4% increased Attack Speed while Dual Wielding Crimson Jewel
* Retribution (Templar Node - 5% increased Attack and Cast Speed)
* Instruments of Virtue (Inquisitor Node - 20% Inc AS if you've Attacked Recently)

Edit2: I just recorded a quick vid showing the diff - currently uploading, should be done in the next 5-10 minutes.

Edit3: Here is the video. Please forgive the quality/cropped screen, I don't usually record things, but felt a visual was helpful: https://www.youtube.com/watch?v=cnT6S0ofTi8&feature=youtu.be Please note, the APS you see in the video are slightly different than the ones listed above, as I changed gear around between my original post and recording the video; although the bug is still evident, as I do not yet reach 3.99 in the video either.

Edit4 It is not a bug w/ the Elder Gloves affixes either. I put on a different pair of gloves + socketed the Frenzy with Faster Attacks to get to 3.91 APS, and had the same problem. TY

Bump - am i missing something here? ty

Confirmed this with my 3.91 APS setup.

My observation is the following (3.91 APS during the whole process):
<Frenzy Attack #> | <Cast?>
1 | +
2 | -
3 | +
4 | +
5 | -
6 | +
7 | +
8 | +
9 | -

After that, the sequence of 6-9 is repeated indefinitely (3 attacks proc, 1 doesn't).

Thank you for contributing.
GGG can we get some acknowledgment of this? We know you're busy.

I use poets pen and have 3.72 aps iirc cant log in to check right now, but I get 3 casts per second with this, its noticably slower at 4.01 aps which is what my build previously had. basically, when I was around 4 aps, I was losing the cast.

I have a feeling that even if you were able to get 4 aps on the dot, you would lose a spell. There is some kinda delay that is making it impossible to get the 4 spells.

At 4.01 aps in pob, my "Attack time" was 0.25 exactly, which should net me all 4 casts per second, but I was actually getting even less then I am at 3.75~ which I think reinforces my idea that what happens is the spell comes out causing it to go on cooldown, perhaps it comes out after the attack is intiating, meaning if your attack time is exactly 0.25 seconds, it hasnt finished cooling down by the time you swing a second time, for the third it procs, and then same for the 4th it hasnt gotta time to cool down

At 3.72 aps, your attack time is is 0.27~ So you swing, your first attack goes on, the cooldown is ALWAYS up for all three swings, because it has leeway. At 3.99 aps your attack time is 0.2506, there is some kinda order of operations that is getting into the way of how the pen procs. The spell comes out after the attack so lets say the spell comes out 0.005 seconds after the attack has intiated, in this case, at 0.2506 attack time, 0.2506 - 0.005 = 0.2456 has passed, meaning its still on cooldown when you intiate the next attack losing the proc.

Sorry if this is messy, Im very bad at explaining myself, but im sure this is because the spell comes out after you have intiated attack, making 4 casts per second on the dot for two spells with two pens impossible as there will always be a tiny delay preventing on the dot from working. 3 casts per second is very attainable however and is what ill be aiming for in all my future pen builds.

oh yeah, I do not use corpse skills. I just use frost bolt and magma orb.

my own post from reddit

To clarify I think this is less a bug and more so an issue of working with very tight windows of cds when trying to maximize the dps if 4aps is possible to work exactly, even mili seconds of delay will greatly throw off the cycle.

The community should instead not build for maximum effectiveness possible, but instead the max you can get even understressful/laggy conditions.

It does break at some point a bit before 3.99 aps. But if it's breaking at 3.8 you're using two poets pen with different attack speed rolls.


When the ingame tooltip calculates aps it takes the avrage of your two weapons. If you have one slow and one fast poets pen it could mean that one of them performs an attack in 230 ms and the other one in 260 ms. This would grant less than 4 aps, but you would still be attacking while its on cooldown delaying every other spellcast. Also make sure you dont have any main hand attack speed increases, not that they're common.

My 3.91 case is with two 100% perfect and thus identical Poet's Pens and the only attack speed I have is from inquisitor, templar start, shadow start, frenzy charges, faster attacks and frenzy itself.

This is definitely related to how server ticks handle attacks and cooldowns.

On my character, everything is fine at 3.8 APS with a single wand, the higher I go from that, the more frequent it starts to glitch out.

Here's my configuration
2 Poet's Pen - 10% and 11% increased attack speed rolls
4.42 buffed APS on character sheet
20% Increased Cooldown Recovery Speed on belt

Testing in a map while fully buffed but just attacking the air (not hitting anything, so I'm getting relatively stable FPS) I get the pattern of 5 casts, 1 no-cast, repeat.

20% increased cooldown recovery speed should give me 20% more casts, up to 4.8 casts per second. My current APS is roughly ~8% lower than that, which should be more than enough to account for the difference in APS between my weapons.

Even assuming the worst case which is caused by a cooldown rounding issue - 250ms / 1.2 = 208.333ms which is rounded to the character sheet value?? of 210ms that still comes out to 4.76 APS which far exceeds the APS of my weapons, including the uneven attack speed.

edit: Under situations of high server/client/network stress such as big Abyss spawns, the proc rate can drop to only 2-3 casts before a no-cast.

As it pertains to your post, if I'm reading it correctly, I don't believe your experience fits this particular bug. I am referencing non-cast attacks at 3.99 APS or slower. you have 4.42 APS, which exceeds the 250MS cooldown on the Pen.
