Attack speed mechanics

[shogigut]

Sorry it seems a noob post, but I do wonder how can I know if I'm at the attack speed cap? I think the latest speed cap is 500%, does that means the max attack speed one can achieve is the base speed divided by 5?

 

Also, how does attack speed stack? I believe it stacks linearly.

[Ironsights]

its not linear. there's a post by (i think) eliwan in the item database(?) that has all the number formulae in it.

 

AS for attack speed caps....its usually around .5 or .6 as far as I can tell, or 2 attacks per second. So if your attack speed is something like 1.9 (-1.3) you are probably at or bloody near the cap.

I think it's just AS / 4 now, for the cap.

 

Below is what I remember:

 

For the Attack Speed stacking, let us ASSUME THE FOLLOWING:

-Your base Attack Speed is 2.

-You have EXACTLY +10% Attack Speed from Agility

-You have +10% Attack Speed from Dominion Standard

-You have +12% Attack Speed from a Serrated Cleaver

 

For this, we do:

2 / 1.1 / 1.1 / 1.12 = 1.476 Seconds per Attack

Or, to put it another way, 10% attack speed bonus boosts your Attacks per Second (and, consequently, your DPS) by 10%. Another 10% boost increases it by 10% of the new value. Say you deliver 1 attack per second. With +10% aspd, you now deal 1.1 attacks per second. Another 10% gives you 1.21 attacks per second rather than just 1.20. A third 10% would give you 1.331 aps rather than just 1.30. So on and so forth. Your bonus from Agility works similarly; each point of agility improves your DPS by 0.29% cumulatively. So to get the 10% bonus in Eliwan's example, you'd need (log_1.0029 1.1) which comes out to about 33 Agi.
