    Why do some items that increase attack speed work, and others don't?

    In Diablo 2, there was a difference between Increase Attack Speed (IAS) on weapons and IAS from other sources (such as Armor/Jewelry).

    I started to wonder about the same in Diablo 3, when I looked at weapons that have an IAS property, such as this axe: http://eu.battle.net/d3/en/artisan/blacksmith/recipe/the-wedge

    As you can see, the item-information states: 1.46-1.47 Attacks per Second, which is more than an axe has without the IAS (1.3 in that case). Equipping such a weapon while having other items with +IAS, won't change that number. This leads me to the conclusion that there might be two separate IAS calculations going on. The IAS on the weapon changes the base weapon speed, while all other IAS is multiplied with that base-speed.

    Which in turn would make IAS on the weapon itself more valuable.

    Does anybody know how the formula for attack-speed works? Are all sources of IAS being treated equally, or is there indeed a difference between weapon-IAS and armor-IAS?

When do these apply? For instance, the Force Weapon rune adds a chance for a knockback effect. Does that mean a Wizard has a chance to cause knockback when casting Disintegrate, when under that enchantment?

  • Possible Duplicate: How is listed DPS calculated when dual-wielding weapons? If I equip a dagger in my mainhand (1.31 APS) and then an axe in my offhand (1.30 APS) my attacks per second go up to 1.51. Makes sense based on this guide. However, when I unequip both weapons, then equip the axe in my offhand first, then the dagger in my mainhand, my attacks per second drops to 1.28. These are the same weapons equipped in the same slots, just in a different order. The same thing happens if I switch it up and do Axe mainhand, Dagger offhand. Why the difference? EDIT: I have

  • I'm playing as a Demon Hunter and recently I was looking at the passive skills when I saw Cull the Weak skill that increases damage against slow enemies by 15%. The question is: does this skill only work with the effects of the other skills(Caltrops, Rapid Fire with Web Shot rune, Entangling Shot, etc)? Or does cold damage on the weapon also count as slow effect for this skill? If so, then a 2-hand Bow with some cold damage, Archery, Cull the Weak and Steady Aim would give a nice +50% damage bonus.
