Diablo – n attack speed cap

diablo-3

While playing around with some item builds, I managed to reach a little over 2 attacks per second. This was a huge increase from the 1.10 APS staff I had been using, and a TON of fun. But realizing that I am only level 19 and only half of my slots had attack speed bonuses, I am sure it is possible to reach much higher levels of attack speed.

Is there a maximum attack speed? Or will we see level 60 characters machine-gunning everything in sight (without Rapid Fire)?

There is no hard cap, but obviously a practical cap based on the base speed of weapons and max values of available IAS bonus.

Fastest base weapon speed: 1.50 (daggers) or 1.60 (1H crossbow)

IAS from 2 rings + amulet: 9 x 3 = 27%

IAS from the weapon: 11% (rare/magic), or 20% (superior quality white items)

6% from legendary items in various slots:

  • Chest: Beckon Sail or Tal Rasha's Guardianship
  • Pants: Inna's Glory
  • Helm: Andariel's Visage or Mempo of Twilight
  • Bracer: Lacuni Prowlers
  • Boots: Boj Anglers

Off-hand: 20% from Dead Man's Legacy for Demon Hunter off-hand

There is also the Shrine of Frenzy which adds a 25% IAS for 2 minutes.

So if you just want the theoretical max weapon speed:

  • Base weapon aps of 1H crossbow: 1.60
  • Bonus for superior item quality: 20%
  • Total bonus from equipment in general: (9 * 3)% + (6 * 5)% = 57%
  • Additional from Dead Man's Legacy for DH: 20%
  • Shrine of Frenzy: 25% (not sure if this is additive with items or multiplicative factor)
  • Focus Mind passive from Enchantress: 3%

Max bonus from items for DH: 57% + 20% = 77%
Max IAS incl shrine = 102% Final weapon speed: (1.60 * 1.20) * 2.02 = 3.8784 aps

I did not include Focus Mind as I don't know how it will apply. This also excludes the effect of skills that add IAS like Barb's Frenzy. (A Barbarian would have to use daggers instead of 1H xbow).
