When I was digging this info, this site helped me a lot. There's a lot of text there, so I'm going to simplify it a little.
So, to avoid further misunderstanding:
(c) all right reserved Xepolite's shithole!
WSM Bug is intended to decrease the requirement of IAS to reach 9-frame trap laying breakpoint without* using BoS.
*Against chars that deal physical damage, we will use Fade, because it gives us DR that can't be taken from other items (102 fcr build). Also, we need to stack our IAS to neutralize Clay Golem's slow (will be discussed later). Therefore, the gear for an Assassin (C/C) is chosen in order to achieve maximum trap laying speed without BoS.
Auto WSM is a little trick that makes this bug to be performed automatically, without any manual action from your side.
Firstly, you need to understand how trap laying speed is calculated when using C/C.
IAS needed for 9-frame trap laying speed
Primary claw is the one that is under the gloves.
Secondary claw is the one under the boots.
Look your claw's Weapon Speed (later - WS) on this website. Now fill the values into this table. It's symmetrical, so you can put Primary claw's IAS both to the left and to the top.
The lower the number is, the faster the claws are. Claws with WS=-30 are the fastest, and ones with WS=10 are the slowest.
Let's say you use 2xGteater Talons. Their WS=-30. After looking for a column -30 and line -30 we see a breakpoint of 42 IAS. We need to get IAS NECESSARILY from the Primary claw (above the gloves). There spawns 3 affixes: 20 IAS/ 30 IAS/ 40 IAS. 30 and 40 are good for us, cause we can insert jewel 15 IAS (or Shael) and get 45(55) IAS breakpoint. You can insert jewel 15 IAS (or Shael) in a tiara as well, but do NOT put it in your Secondary claw (boots one)! We don't want any additional IAS on that claw, it doesn't "count". Even 0 IAS is good for us. If there already is IAS on — nothing terrible, just don't additionally insert Jewel or Shael there. After all, Primary claw's IAS must be more than the Secondary.
Now we have the maximum possible trap laying speed — 9 frames.
As you can see from the table, we are mostly interested in "fast" Claws (-20,-30 WS). The best options here are Greater Claws, Greater Talons (Runic Talons and Feral Claws, however, have high requirements). With Greater Claws and Greater Talons, we will only need 42-63 IAS, that is not difficult to achieve. With two slow claws (10,0 WS) will have to gain 125-174 IAS (damn that's a lot D:).
If you a still doubt, whether you chose right claws - test them on this calculator.
If you are playing W/S Assassin (Hoto+Spirit) you will always use BoS. You will need at least 16 lvl BoS for 9 frames.
Here is a perfect option for a classic ls+fb Assassin:
The disadvantage of this option is that, firstly, we have to insert Jewel (or Shael) in the gloves-claw socket. Secondly, if our opponent has "Slows target by xx %" or Clay Golem, your trap laying speed will decrease.
This should be mentioned:
Some rules say "Clay Golem is banned against IAS-dependent characters, including Traps-Assassin". However, thanks to WSM Bug, Assassin will gain tons of overstacked IAS, so Clay Golem won't affect our speed at all. Decent Assassins will always use WSM Bug and will never say anything against Necro with Clay Golem (besides skilling Fire Golem is a waste of skill points. No decent Necro would ever do it).
So let's take a look at...
Thing is that when we equip our claws (roughly after each swap or BO it re-equips) — claw under gloves equips first and becomes our Primary claw and the claw under the boots becomes our Secondary claw. After doing a little trick (flashing our gloves-claws),
we make the boots-claw equip first, so it becomes Primary. After we put back the gloves-claw, they become our Secondary claw. So, generally, they swap.
The result of this is a change in the formula for calculating trap laying speed. Now we should use another table.
Take your claw's WS and fill it in a new table. As you can see, it is better to have fast claws (preferably -30) on the right and slow (0, 10) on the left. Then we will only need 13-19 IAS on our (already) boots-claw. We will most likely easily get it without Jewel or Shael (claw's IAS affixes are 20, 30 or 40 IAS). Here is an extra socket.
If you a still doubt, whether you chose right claws - test them on this calculator.
For a classic Traps-sin, the ideal option would be:
As you remember, IAS of our (already) left claw won't matter, cause it became Primary claw. On the boots-claws, we will only need all 13 IAS.
Slow (Clay Golem // Arachnid Mesh// Nostefaru's Coil)
In a duel vs Necro, we will use BoS in order to neutralize the "slow", so Clay Golem won't affect our trap laying speed.
I didn't want to go into unnecessary details (numbers) but now I have to.
Generally, there is such a thing as AWSM. It is calculated based on WS of your claws by the following formula:
(( [RC] + [LC] ) / 2 ) + ( [RC] - [LC] ) - the formula for AWSM after WSM Bug.
RC - Right claw
LC - Left one
Assassins mainly use 2 options:
- War Fist + Greater Talons
- Scissors Quhab + Greater Talons
Let's use the formula for these two most popular options:
- War Fist + Greater Talons = -50
- Scissors Quhab + Greater Talons = -45
Slow from Arach and Nostefaru cuts our AWSM by 10, so it becomes -40 / -35.
Conclusion: to overstack the slow from Arach and Nostefaru, we should have 26 / 34 IAS. BoS is not needed.
Slow Clay Golem cuts our AWSM by 50, so it becomes 0 /5.
Conclusion: to overstack the slow from Clay Golem, we should have 11 / 18 IAS (18 lvl BoS).
HotO's AWSM is -10. You will need at least 16 lvl BoS for 9 frames.
Slow from Arach and Nostefaru cuts our AWSM by 10, so it becomes 0.
Conclusion: we should insert a 15 IAS jewel in our Circlet to reach 9 frames.
Slow Clay Golem cuts our AWSM by 50, so it becomes 30 (actually, 40. but capped at 30).
Conclusion: we do nothing and just wait until slow passes (34 seconds iirc), cause getting 58 IAS (20 lvl BoS) is impossible for 174 Sin.
In the case of a DC Assassin, we also use Dragon Claw (1 point) and deal physical damage, so the base claw's damage matters to us as well. The most powerful slow claws are Suwayyah and War Fist. As for the fast — Greater Talons and Runic Talons (in fact, even though the average damage of RT is bigger, after the PvP penalty and DR the difference will be like 10 HP. Also, RT has too high requirements). Greater Claws and Feral Claws will match nicely with WF (10 WS), but with Suwayyah (-20 WS)(look for the line "-20" and column "0") after Golem's slow we will have 20 AWSM. At 18 lvl BoS, we will need 40 IAS.
Here is a perfect option for a DC-Assassin:
Chaos's preferable base is Suwayyah. WF has bigger damage, but it can only have 2 sockets.
By the way, there is a small addition when playing with Chaos. Besides wanting to achieve the 9-frame trap laying speed, we will also need to have a WW breakpoint — 4 FPA for each claw. It is calculated separately for each claw. You want to have a number less than "-13" when you subtract you claw's WS from its own IAS.
For Suwayyah: 0-35 (IAS on Chaos) = -35. Chaos will hit every 4th frame.
GT: -30 - (your IAS here). So there is never a problem with fast claws.
After all, on the left, we have Chaos in Suwayyah (35 IAS), on the right, fast claw (GT, RT).
A small disadvantage of WSM Bug is that you need to do the claws flashing manually before every duel (and after each swap). Therefore, if you are lazy - you can do ...
Auto WSM Bug
The trick is to insert a "+X to dexterity" jewel into our right claw. With a proper selection of claws and your dexterity, your left claw won't be able to equip without the dexterity of the right claw. In that case, the right claw "has" to equip the first. And this is exactly the condition of the WSM Bug.
For example, our Assassin has 24 basic dexterity, 20 from Torch, 20 from Anih, and 25 from Shadow Dancers. A total of 89 dexterity.
War Fist (98 Dex Req) can't be equipped. So, we insert a 9 dex jewel in the right claw. Now the right claw will let the left equip.
An indicator that Auto WSM Bug works on your Assassin is that your left claw will become red if you lift up the right claw. If it happens, it means you did everything correctly. So after each swap, you won't have to flash boot-claw. WSM Bug will be done automatically.
For a DC Assassin the best option is:
These claws are Ethereal. It will be hard to find similar claws on a normal server. Requirements will be others for a non-eth claw, and therefore the value of your dexterity.
For example, when using non-eth WF (dex Req 108) in addition to the perf Anihm, perf Torch, and perf SD (total of 85 dexterity) you will need to get 15 more dexterity (from rings, for example) for 100 dexterity. After inserting a 9 dex jewel in your right claw, your dex will become 109 and WF will be able to equip.
^all this is assuming you want to have base dexterity. If you don't have all the items I mentioned above — you can just put some points in dexterity, but in that case be sure to choose a right armor base for Strength Bug.
Here is a perfect option for a WW-Sin (Ghost/Hybrid):
Don't forget that AWSM Bug is intended only for convenience. For a serious face duels/bet duels, where every detail is important, it is advantageous to gear something like this.
In this case, affix "+2 to Assassin Skills" is sacrificed for 50% OW, but it's not about that.
In a serious face duel, it would be better to insert Um in the right claw for an additional 25% OW. Flashing gloves-claw before the duel for additional 25% OW is definitely worth it.
Good Luck and Have Fun!
Wish you good luck in all your endeavors!
