Arcanum of Rapidity as a quest objectiveEdit


  • The Arcanum used to be needed for the special class-specific Zul'Gurub enchantments. However, the requirement was removed in Patch 1.11.
  • The quest to get all Arcanums are repeatable.
  • Attack speed increases do stack with each other, you can get two librams, a counterweight and haste to gloves enchant, and they all stack.
  • "Haste rating" is now used instead of a straight percentage buff. According to Blizzard, items converted to the new rating system have no direct changes in their effects.
