The Arcanum of Rapidity is a quest reward from the quest Libram of Rapidity which starts with Lorekeeper Lydros in Dire Maul. To complete the quest, you must turn the following items:
*1x Libram of Rapidity
*1x Pristine Black Diamond
*2x Large Brilliant Shard
*2x Blood of Heroes
==As a quest objective==
*The Savage Guard - Arcanum of Rapidity
==Notes==
*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.
