From Diablo Wiki
- Damage Bonus: This determines how you multiply the item damage by your stats to reach the actual damage. Multiply by the listed value per 100 points in that stat. All bows are 100 Dex, almost all melee weapons are 100 Str, most throwing weapons are 50/50.
- Weapon Speed: A relative comparison to other weapons of the same type. 0 is the base -10, -20, etc is faster, 10, 20, etc is slower, always in increments of 10. Each 10 is equivalent to an SIAS item. Previously items were listed with WSM modified by IAS on the items, we have revised this to show the Weapons base speed (WSM) before ANY IAS.
- Range: Relevant to melee weapons only. From 1 (least) to 5 (most) in D2X. Numbers are fixed across item classes: a 3 javelin = a 3 sword = a 3 hammer, etc.
