Weapon Speed is a Diablo II item stat determining how quickly a weapon is to use between swings/fired shots.
How it WorksEdit
Weapon Speed is relative comparison to other weapons of the same type, and is always written in increments of 10.
0 is the base -10, -20, etc is faster, 10, 20, etc is slower.
Each 10 is equivalent to an SIAS item. Previously items were listed with WSM modified by IAS on the items, we have revised this in the wiki to show the Weapons base speed (WSM) before ANY IAS.
