How does attack speed work?

  • #1
    If you look at a weapon, both here and on arreat summit, it says something like base speed: [10]. What does that mean exactly? And how does IAS affect it?

    I'm not sure what you mean. The base 10 is normal attack speed I would imagine. If a weapon has 10% increased atk speed I would guess it becomes a "Fast attack speed" weapon. 10 more for very fast. Or something like that.

    If I recall correctly...I believe my polearm was normal attack speed. Base 10 I assume. With 30% IAS it became "Very fast attack speed".

    they have something to do with frame rates, a [0] is i guess the norm, but some weps, depending on size/weight/etc..., have different base speeds. like [-10] or [10], what i think this means, is the amount of ias you need to reach an ias breakpoint for a certain character.

    i know this from my zon, which uses a gmb faith [10], and needs something like 95 ias to reach the max 7 frame ias. while a mat bow faith only needs something like 45 ias to hit that 7 frame breakpoint.

    All I know is that the lower the number, the faster the weapon. IAS is pretty complicated, because it depends on a boatload of factors, including class, which weapon is being used, which skill is being used, the IAS on the weapon itself, and IAS on other gear or from skills (like Burst of Speed or Fanatacism). For an example of this, look at a claw. For an Assassin, they're all (I believe) "Very Fast," but for other classes, they're "Very Slow" (of course this doesn't matter since other classes can't equip it, but it's an example). Most, if not all, weapons vary in this way. There's a link to an IAS calculator on the DiabloWiki.com - Breakpoints Breakpoints page, but I don't know if this will help answer your question. You can also read through this thread if you dare, though it is written specifically for Assassins. I haven't pored over it in detail, so I don't really know all what it contains.

    Ok. Assuming you only use one weapon, with no additional gear or skills, how does it work.

    Say that a weapon has [10] in base attack speed. Do classes have different actual attack speeds based on that 10? Say if a Sorceress and a Barbarian both swing the same weapon with [10], wil it swing equally fast, or does that differ from class to class?

    And suppose that weapon had 10% IAS, what does that mean? How do you apply that to the [10]?

    The Assassin post doesn't seem to actually explain how it works, only what the results are :S

    I don't know how a weapon could have [10] as attack speed, because it differs per class. You can't say "oh this weapon has base [10] so that means a sorceress would be [20] and a barbarian would be [0]"... Because each weapon has different numbers for each class. An easy example of this is a Barbarian is faster with an axe, while an amazon is faster with a spear.

    Btw claws aren't all very fast for assassins. The Scizzor Katar is actually Very Slow but has high damage, which makes it a really good weapon because it's easy to hit the IAS breakpoint with an assassin which means the weapon speed isn't as important as the damage. But it was a good example.

    Well take the DiabloWiki.com - The Gnasher The Gnasher. It displays as [10] base weapon attack speed. Which must span across classes, since veryone can use an axe.

    However, checking the DiabloWiki.com - Hand Axe Hand Axe, it displayes as normal for everyone except for sorcs.

    So different numbers mean different things depending on which weapon typ it is then?

    Yes, that's right. The numbers they show on the uniques page are apparently only an indication of how fast that unique axe is compared to other unique axes (??). If you want to know the actual speed of the weapon depending on which class you're using it with, look at the base item that corresponds to it. Don't forget to factor in any IAS on the unique though...

    Your example, the Gnasher, should show up ingame as "fast" for any class but the sorceress.

    It's weird that they don't just show those class speeds on the uniques page, but oh well. The info seems to be taken straight from the Arreat Summit site :/

    But isn't it so that ANY axe will with [10] will in fact equal "slow" for for the sorc?

    Indeed. I think I copied it in fact :P

    That seems to be the case, the data matches when you compare the tables. So it's not like the number doesn't mean anything. It's just that it's really useless information xD

    Indeed. I think I copied it in fact :tongue:

    ^^ Well I meant it's weird that the Arreat Summit site shows it like that :whistling:

    I think it works something like this, which is taken from my DiabloWiki.com - WhirlWind Sin WhirlWind Sin build guide. This info was gotten from that same post I linked before, but...
    The fastest breakpoint for Whirlwind is 4 frames, which requires a Modified WSM (Weapon Speed Modifier) of -13 or lower. Modified WSM is equal to the WSM of your claw (the base attack speed - 0 for a Suwayyah) minus the amount of IAS on the claw. Since both recommended runewords have more than 13 IAS on them, you will always be Whirlwinding at the fastest breakpoint. IAS from gear besides the claws (such as on Highlord’s Wrath) is not taken into account when Whirlwinding.


    So from that, I gather that the number in brackets is subtracted from by the amount of IAS on the weapon itself. I'm not sure if IAS from other gear works in the same way for normal attacks or attacks other than WW.

    When I was making the new templates for the Unique Items, I was running into this issue as well. Since the Unique page says [#] and the base item page says "Fast, etc." I couldn't tell if any IAS on the Unique had been factored in to the base stats on the Unique page. Obviously, the Enhanced Damage on those items is, but it's hard/impossible to tell if the IAS has been. I know for DiabloWiki.com - Humongous Humongous, the addition to requirements isn't applied to it, so I fixed that in the new DiabloWiki.com - Template:Humongous (Diablo II) Template:Humongous (Diablo II). But IAS is a whole 'nother issue... :confused:

    I'm not sure, but from what I've always assumed, when people talk about breakpoints for melee skills they talk about a number like -200

    And as far as I'm aware it works more like FCR than you might think. In that it actually subtracts not a percentile from your weapon swing but a set number. So a weapon with base -10 weapon speed, a blue of it is picked up and it has a 10% IAS modifier on it, I have always assumed that that means that it is -20 weapon speed (taking nothing else into account).

    I have used this model to on most of my characters to help get them to breakpoints. But I'm not sure if it's the correct one. And google doesn't help me help you :(

    P.S. Yeh I'm pretty sure that's incorrect, but I've used it like this without calculators for all of my characters so... w/e
