Hi guys, 1st post here. :)
I play with The Basin on the Stormrage server. I came here to post this hoping someone has an explanation, it seems there are alot of technically minded people, maybe there's just some game mechanic I'm not aware of.


Specifically, I was testing the Paladin talent Reckoning in conjunction with a Flurry Axe and Hand of Justice trinket.

Reckoning: 10% chance after being hit by any damaging attack that the next 4 swings within 8 seconds will generate an extra attack.
Flurry Axe: Grants 1 extra attack on your next swing.
Hand of Justice: Chance on melee hit to gain 1 extra attack.


There appears to be some bug with this combination, as I am not always granted extra attacks when I should be. Here is a snippet from a combat log that managed to capture what should have been all 3 effects firing in a single round.

Also this log shows another potential bug with Reckoning in that it is either: occasionally giving 5 swings instead of 4, or that if you have the Reckoning buff active and gain it again, it does not log any message for this event.

I can provide a complete log if anyone would like to see it.

Here is another snippet of Flurry Axe + Reckoning triple hit, showing all 3 SoR hits too. I find it interesting that the SoR hits here come in at almost .3 seconds later. Why?

I'd imagine it's because they need to check if your attack hit before triggering SoR. If they were completely simultaneous, you'd get SoR procs on misses/parries/dodges. (which wouldn't make sense, as well as being a damage buff)

Some procs happen instantly (sword spec extra attacks did last I checked), while other procs happen with a slight delay (almost all procs including SoR and Hand of Justice).

Here is a made up combat log of how Sword spec extra attacks and Hand of justice worked the last time i checked them (1.12), using a 2.0 speed sword.

00:00 you hit mob
02:00 you hit mob
02:50 you gain extra attack from HoJ
02:50 you hit mob
04:50 you gain extra attack from Sword spec
04:50 you hit mob
04:50 you hit mob
06:50 you gain extra attack from sword spec
06:50 you gain extra attack from hoj
06:50 you gain extra attack from sword spec
06:50 you hit mob
06:50 you hit mob
06:50 you hit mob
06:50 you hit mob
08:50 you hit mob
09:00 you gain extra attack from hoj
09:00 you gain extra attack from sword spec
09:00 you hit mob
09:00 you hit mob
09:00 you hit mob

HoJ would proc "instantly" if it came off of another sword spec swing, but would have a delay included if it was off of a regular swing. All multiple procs from the same (or subsequent since you cannot tell a difference) swing came at the same time

Any idea what the reasoning is? I know that at least one type of "extra attack" was described as resetting the swing timer. If so, I wonder if parry (assuming it does this as well) might cause some issues?

All "extra attacks" reset the swing timer unless they are yellow damage. It's just that sword spec resets it immediately and HoJ resets it with a slight delay most likely caused by server lag(you are probably referring to the resetting the timer from offhand attacks, but honestly, if it did not, it would be overpowered and due to the introduction of combat potency, they cannot actually program it correctly and have it proc offhand swings now). The difference is probably that one is being checked client side and one is checked server side. Patch ~1.10 introduced most extra attacks with the extra delay, I assume this was done to counter would be exploiters from instagibbing any mob. This delay was removed from sword spec in 1.12, but not from HoJ. The reason the delay would be removed is because the mechanic resets the swing timer causing your actual gain in dps from an extra attack to be based upon server lag. This is clearly broken since sometimes the lag was over 1 full second.

Keep in mind, most of my knowledge of the actual mechanic and how its calculated is speculation, but it is based on educated guessing.

I always consider "chance to get an extra attack" as "chance for the delay before your next attack to be reduced to 0" as far as game mechanics are concerned(since the patch that changed extra attacks to work exactly in this way, obviously).

Actually now that I look at this block again, is this actually all a single "round" of combat?

It would mean putting a .6 second delay between the inital attack and the proposed Flurry / HoJ proc. But it would explain why there was no Reckoning there. If so then would it mean that swing timer got reset to the time that Flurry / HoJ proc went off? That is pretty huge considering that Flurry Axe is only 1.5s, so if you're adding on .6s onto that from the inital swing because of the procs... I think I will need to go back to the full log and see when the next attack is at.
