In Diablo II: Lord of Destruction, Whirlwind is affected by weapon speed as follows. After you click to start your Whirlwind attack, the game checks for a hit on a target in range at the 4th and 8th animation frames (recall that the game runs at 25 frames per second). After the first two "free" hit-checks, the frames elapsed in-between subsequent hit-checks will depend on your weapon speed. Note: increased attack speed from items outside your weapon DOES NOT affect whirlwind - only the speed of the weapon itself counts. The dependence on weapon speed is obtained by subtracting your weapon's increased attack speed (IAS) to its base weapon speed (the number between square brackets listed in the weapons section of the Arreat Summit) and checking where the number you obtain fits in the following table:
One-handed weapons
Breakpoints: 15, 10, -10, -34.
Number of frames in-between hit-checks after frame 8: 12, 10, 8, 6, 4
Two-handed weapons
Breakpoints: 15, 0, -10, -30, -60.
Number of frames in-between hit-checks after frame 8: 14, 12, 10, 8, 6, 4
Examples:
1: War pike of quickness (two-handed weapon)
Base weapon speed: 20
Weapon increased attack speed: 40
Whirlwind speed: 20 - 40 = -20
Breakpoint reached: -10
Number of frames in-between checks: 8
Hit-checks at frames 4, 8, 16, 24, 32, etc.
2: Falchion (one-handed weapon)
Base weapon speed: 20
Weapon increased attack speed: 0
Whirlwind speed: 20 - 0 = 20
Breakpoint reached: none
Number of frames in-between checks: 12
Hit-checks at frames: 4, 8, 20, 32, 44, etc.
3: Grandfather colossus blade with 'Shael' (one-handed weapon)
Base weapon speed: 5
Weapon increased attack speed: 20
Whirlwind speed: 5 - 20 = -15
Breakpoint reached: -10
Number of frames in-between checks: 6
Hit-checks at frames: 4, 8, 14, 20, 26, etc.
Note: two-handed swords are treated as one-handed weapons for Whirlwind purposes, regardless of the sword being held in one-handed or two-handed mode. The above calculation for Grandfather therefore holds for any way the sword is held.
