What is WSM?

I'm studying EIAS<>IAS Conversion.

I find information about EIAS but I don't understand this.

That web page says,

"Necessary ?EIAS = Target ?EIAS - Skill ?EIAS + WSM"

What is meant by WSM and How can I see information about WSM.

WSM, Skill EIAS... Help me!
 
Re: What is WSM?

Skill eias is the ias you find on skills like fanaticism and burst of speed. Frenzy and perhaps a few other (doesn't the werewolf have something like this too?) It's the number that is listed (eventhough it's listed as ias and not eias).

WSM is the weapon speed you find on weapons. In game it says something like fast attack speed or normal attack speed. You can get this in number too like on the summit. you'll see that there are different number for different weapons. -10 for the fast bows and 10 for the slow bows. Again, eventhough it may be listed as ias, it's eias.

That should answer all your questions.


P.S. May I ask why you are studying that. For use, it's much easier if you look up a table where people have done the calculations for you are use a weapon speed calculator.
 
Re: What is WSM?

Thank you NASE.
I like studying principle, algorithm and 'how to calculate'. I believe that "basic is important."

and.. In Korean(Do you know South Korea?) Diablo II community, there are few information about Diablo II. Almost Korean diablo players have no information like 'How to calculate poison damage', 'NextDelay' even 'What is Double Damage Formula'.

I write many thread about D2 strategy in Korean Diablo II Community. but I haven't lots of knowledge to write advanced strategy. That's why I study those basic things.

Thanks.

"Necessary ?EIAS = Target ?EIAS - Skill ?EIAS + WSM"
Just to make it clear:

EIAS = (120 * IAS)/(120 + IAS) + Skill_IAS - WSM

EIAS: The amount of effective increased attack speed you have, this number is what is determines what breakpoint you reach, and skills have different required EIAS to reach a specific breakpoint. Some skills are a bit special though (thinking of whirlwind and wereform attacks).

IAS:
Increased attack speed from equipment.

Skill_IAS: Increased attack speed from skills (fana, BoS etc).

WSM: Weapon speed modifier, a negative such modifier means a faster weapon (as you see from the formula a WSM of -10 gives +10 EIAS). Can be found on arreat summits item pages.

Note that diablo 2 will round numbers down, so keep that in mind too.



I don't know how that page wishes to define "Necessary ?EIAS" and "Target ?EIAS" but I'd say they're just making it harder then it is.

It's correct what the site says. "Target ?EIAS" is how much eias you need to gain a certain breakpoint. "Necessary ?EIAS" is the eias you need not based on the weapon speed and not based on skills, thus based on equipment.

What you write as "(120 * IAS)/(120 + IAS)" simply is the "Necessary ?EIAS" in the site.

Alright, thanks for clearing that up. I'd say they should avoid using delta in the name though ...



 
Re: What is WSM?

Umm.. I have more question. This Website (Basin Wiki) says,

---------------
Necessary ?EIAS = Target ?EIAS - Skill ?EIAS + WSM

From your target ?EIAS, subtract any quantities of ?EIAS from skills. This can come in the form of Skills that increase your attack speed such as Burst of Speed and Fanaticism and curses that slow your attack speed like Decrepify. Attack speed increasers have a positive ?EIAS while speed decreasers have a negative ?EIAS.

From that amount, add your weapon speed modifier (WSM).
-If you are single wielding, your weapon speed modifier is your weapon's WSM.
-If you are dual wielding and the weapon in your left inventory slot is your main weapon, your weapon speed modifier is (LeftWSM + RightWSM) / 2.
-If you are dual wielding and the weapon in your right inventory slot is your main weapon, your weapon speed modifier is (LeftWSM + RightWSM) / 2 - LeftWSM + RightWSM.

The resulting value is your Necessary ?EIAS. This is the amount of speed increase you need to make up with the IAS from your equipment. If its value is negative, you don't need any additional IAS from your equipment. If it is positive, look up this value in the table below to get the amount of IAS you'll need to have in order to reach the Target ?EIAS.
---------------

If I equip Colossus Blade(WSM=[+5]) on left hand and Phase Blade(WSM=[-30]) on right hand, Following Formula #3( My WSM=3/2*RightWSM-1/2*RightWSM ), My Phase Blade's WSM and Colossus Blade's WSM is [-22.5]=[-22]?
