Kali, could you please confirm the attack speed with single weapon style and rune arms?
I was expecting to use it to get the full boosts from
feat line +
attk speed drive from mtech +
attk speed boost +
ran it on the v2 builder, but it does not seem to stack once you go runearm. not sure it that’s a bug or a reality in game.
if it’s a bug, would it also stack with monk air instance on top of all three mentioned above?
Hey there

Happy to help with this, as stacking bonuses can be quite confusing.
For the sake of clarity, and to help those who might be new to the game and who might come to read this, I'll try to cover some basics too:
So the Single Weapon Fighting feats grant a
combat style bonus to attack speed: max
+30% with Greater Single Weapon Fighting feat
Single Weapon Fighting requires fighting with a single one-handed weapon, and wielding only an orb,
runearm, or nothing in your off hand, so just to confirm this combat style bonus above will apply.
attk speed drive from mtech +
attk speed boost +
The bonuses you listed here ? are all
action boost bonuses to attack speed, so they should
NOT stack with each other. Only the highest amount normally counts:
The Machrotecnic tree grants:
T5 Armor of Legends: Speed Drive =
+5%. This stays active while the Epic Mage Armor buff is on (and it has a long duration)
T5 Epic Moment (Maximum Overdrive) grants a short temporary
+30%.
So in the scenario where you go Machrotecnic T5 and take the Haste Boost from somewhere (e.g. Vistani T2), you'd have:
- 5% action boost speed on all the time while you have Epic Mage armor cast on you
- this would increase to 30% every time you use the haste boost (and you can have quite a few charges of that with the right investment)
- this would increase to 30% when you use the Epic Moment Maximum overdrive, and even if you use a Haste Boost at the same time, it would NOT stack up to 60%
That's based on my general experience and knowledge of this. I have not tried using the Epic Moment + haste boost myself, so can't confirm with full certainty based on doing it in game.
So far,
combat style bonus (30%) +
action boost bonus (+30%) =
+60% achievable attack speed
if it’s a bug, would it also stack with monk air instance on top of all three mentioned above?
The bonus granted by the monk air stance is an
enhancement bonus to attack speed = 15%.
This type of bonus is the same that is granted through other popular sources (e.g. haste spell, Speed items and Topaz of speed augment). Once again, they should
NOT stack with each other, only the highest amount counts.
Personally speaking, for a bonus type that is so easily acquired elsewhere, I don't find all the investment needed to get the air stance worth the effort :
- at least 1 monk level, which involves multiclassing and, as a minimum, losing the capstone core
- since the stance only works while centered, being restricted to using only cloth armor and monk-centered weapons
- spending 3 feat slots to acquire the Grandmaster of Forms feat
So far,
combat style bonus (30%) +
action boost bonus (+30%) +
enhancement bonus (+15%)
=
+75% achievable attack speed (45% all the time, and an extra 30% while under the effect of an action boost)
I am fairly certain the only way to currently push this speed further is by going Vistani 41 to get the capstone (C6) which currently grants +5% attack speed when using melee and throwing weapons: this stacks with everything, and is currently NOT restricted to daggers/kukris, so all weapon types apply. This stacking bonus is one of the key reasons (amongst other aspects such as doubletrike and haste boost) the Vistani 41 option seems popular with some min-maxers/ 'meta' players out there.
Though it is possible to go C6 in Vistani and T5 in another tree, this is:
- a very significant investment
- at least 41 to get Vistani C6
- min 30 APs to be able to spend points in T5 of another tree
- let's say around 5 APs to spend in T5 (otherwise, why go to T5?)
- that's a commitment of around 76 action points
- and is a bit restrictive (especially if you do not have a ton of past lives), since the you'd be restricted to mostly 2 trees
So in this scenario,
combat style bonus (30%) +
action boost bonus (+30%) +
enhancement bonus (+15%) +
5% Vistani C6 boost
=
+80% achievable attack speed (50% all the time, and an extra 30% while under the effect of an action boost).
Apologies if the response was a bit lengthy, hope it was helpful.
I will work on a response to the questions you sent in the other threads soon: I got to get back to work
