How to check dual wielding Whirlwind FPA:1) Open the link:
https://warren1001.github.io/IAS_Calculator/2432) Choose Class
3) Choose Primary Weapon (Weapon 1)
4) Choose Whirlwind
5) Add "Slowed By" or/and "Chilled" optional, if you wanna check the influence of slow effects
6) Check the table for needed IAS (Weapon 1 IAS + Gear IAS) to reach FPA
7) Write down / save the reached FPA for Weapon 1
8) Choose Primary Weapon (Weapon 2)
9) Add "Slowed By" or/and "Chilled" optional, if you wanna check the influence of slow effects
10) Check the table for needed IAS (Weapon 2 IAS + Gear IAS) to reach FPA
11) Write down / save the reached FPA for Weapon 2
12) Calculate: (Weapon 1 FPA + Weapon 2 FPA) / 2 (if its .5 then round up)
13) The result is the FPA for both weapons
Example: FPA 1 (4) + FPA 2 (5) = 9 / 2 = 4.5 -> 5 rounded up -> Both of your weapons will have a 5 FPA Whirlwind
FPA Illustration: 4 FPA = 6 hits per second | 5 FPA = 5 hits per second | 6 FPA = 4 hits per second
Note: The calculator for whirlwind as a barbarian or assassin is correct, but some other features and minor bugs gets updated in the future!
