1.0 Introduction
This work is an updated and corrected version of the tables in the original thread by JRichard. Obviously this thread is based on his excellent work, my contribution is re-formatting and correcting errors. JRichard's Site is still active. It explains much more than this thread about the mechanics behind these calculations, for those that are interested. Be aware that there may be errors contained in some of the tables on his site, I haven't checked them directly.
The Latest German Weapon Speed Calculator by Titanseal calculates all Assassin attacks correctly to my knowledge. Make sure that you have two claws equipped for Dragon Claw calculations or the skill is not listed. For most people this is the best and easiest method of calculating attack speeds.
Personally I sometimes find tables easier, particularly when planning an assassin that uses Burst of Speed. You can look at a table and decide if to hit the breakpoint it is better to put some hard points into the skill, or maybe sacrifice an equipment socket for a Jewel of Fervour. If you have MS Excel, the complete spreadsheet with all these tables is available here. The Excel has the advantage that you can enter EIAS values for alternative breakpoints and re-calculate the table.
1.1 How IAS required is calculated
The IAS required to hit a given breakpoint is defined by the following formula (I use the MS Excel notation)
IAS = ROUNDUP((120*(EIAS - Skill_IAS + WSM))/(120-(EIAS - Skill_IAS + WSM))
IAS - This is the additional IAS (ie from weapon or equipment) required to hit the breakpoint. Remember that if you are dual wielding claws, only the IAS on the primary claw counts.
EIAS - EIAS required for the breakpoint. The tables for this are listed for each skill.
Skill_IAS - This is the EIAS bonus that you get from BoS (or Fanaticism). The values are defined in section 1.2.
WSM - Weapon Speed Modifier - how quick your weapon is. See section 1.3.
1.2 Correct BoS Values (EIAS)
These are the correct values for the Burst of Speed EIAS bonus, as discussed in this thread. Thanks go to RTB and Stephan for their input into that thread.
Code:BoS Level Skill_IAS 0 0 1 21 2 27 3 31 4 34 5 37 6 39 7 41 8 42 9 44 10 45 11 46 12 47 13 48 14 49 15 50 16 51 17 51 18 51 19 52 20 52 21 53 22 53 23 54 24 54 25 54 26 55 27 55 28 55 29 55 30 55
1.3 Weapon Speed Modifier (WSM)
Weapon Speed Modifier (WSM) defines how quick your weapon is. Values for all weapons are available on the Arreat Summit, but I have included all claws and some of the other more popular weapons in the table below.
If you are using two claws, you need to use the average WSM of your two claws.
eg. You have a Runic Talon (WSM -30) and a Feral Claw (WSM -20). Average is (-30 + -20)/2 = -25.
Exceptions to the averaging rule for dual wielding claws:
1. WSM Bugging (see section 1.4).
2. Using Normal Attack or Whirlwind. In this case each claw hit is calculated seperately.

1.4 Weapon Speed Bugging
Below is a good explanation of weapon speed bugging by TienJe, from his Ghost Assassin guide:
"WSM bugging is a little trick used to lower the Average WSM of your two claws, lowering the IAS requirements for trap + non-WW animations. It works by placing your secondary claw in your inventory first. That means that after you switch to your weapons, lift and replace your glove-side claw, and it’ll bug your WSM.
Instead of just averaging the WSM’s of the two claws, your AWSM = average + (right WSM – left WSM). So, for example, if you use a Runic Talon (-30 WSM) in the boot-side slot and a Suwayyah (0 WSM) in the glove-side slot, if you bug the WSM, you’ll have an AWSM = -15 + (-30 - 0) = -45 instead of -15 like you would if you didn’t bug it. It’ll help you reach your trap IAS BP’s if you use a slow claw on one hand. If you look at the equation, it’ll tell you to make sure that if you DO use a slow claw, make sure the fast one is in the secondary slot, so when you bug it, it makes your AWSM faster. Otherwise, it’ll actually slow down AWSM. To simplify, a chart is included below, showing the AWSM’s for every claw combination after WSM bugging.
In summary, put fast claw in secondary slot, slow claw in primary slot, and lift and replace your slow claw to bug it. Every time you switch weapons, it replaces the primary claw first, so you’ll have to rebug it. Note that after WSM bugging, the glove-side claw becomes secondary, and the boot-side claw becomes the new primary claw."Code:AWSM after WSM Bugging ¦ Boot-Side Claw WSM ¦ 10 0 -10 -20 -30 ________________¦___________________________ Glove- 10 ¦10 -5 -20 -35 -50 Side 0 ¦15 0 -15 -30 -45 Claw -10 ¦20 5 -10 -25 -40 WSM -20 ¦25 10 -5 -20 -35 -30 ¦30 15 0 -15 -30
This information is repeated in Shuko-Jutsu - The Art Of The Claw, along with some worked examples of WSM bugging.
1.5 How to use the tables
1. Work out your WSM, as described in section 1.3. Remember to take the average WSM if you are dual wielding claws. If you are using two claws and are Weapon Speed Bugging, refer to section 1.4.
2. Read down the appropriate column to find out how much IAS for a given level of Burst of Speed. Remember that only the IAS on the primary claw counts.
3. If you are using Fade instead of BoS, your BoS level is 0.
4. IAS only counts if it is on the primary claw or in your equipment. IAS on the secondary claw has no effect, except for Whirlwind or normal attack.
An Example:
I'll use the example of a Phoenix Striker using the Natalya's Odium set, as it is a fairly common scenario.
Natalya's Mark is a Scissors Suwayyah, so has a WSM of 0.
I decide to use Bartuc's (Greator Talon, WSM -30) as my off hand claw.
My average WSM is 0+ -30 = -15.
Let's assume I put only one point into BoS.
Nat's set give a total of +5 to Shadow Disciplines - +3 form the set bonus, +2 from the armour.
With the bonus from the set, that means I cast it at level 6.
I look at the table for Phoenix Strike, and read down the -15 WSM column until I get to BoS level 6.
This tells me I need 19IAS to hit the 7FPA breakpoint.
Natalya's Mark has 40IAS on weapon, so hitting 7FPA is no problem, as long as it is in the primary position.
I'm going to use Dragon Claw as a finishing move, so this time I look at the table for Dragon Claw and again read down the -15 WSM column until I get to BoS level 6.
This tells me I need 54IAS to hit the 10 Frame DC breakpoint.
Natalya's Mark has 40IAS, so either I need more points in BoS, or some more IAS. A Jewel of Fervour in the weapon / armour would do the job, as would some gloves with 20IAS. Alternatively I could put another 5 points into BoS, giving me a cast level of 11. This would only need 40IAS, which is already covered by Nat's Mark, meaning I need no additional IAS in my gear.
Just to clarify, Nat's Mark must be in the Primary position (above the gloves) in this example. Even though you have the same claws, the IAS from Nat's Mark does not count in the secondary position (above the boots). If I did for some reason decide to use Bartuc's as the primary, I would need 19IAS for the 7FPA PS and 54IAS for 10 frame DC.
