Created by Blizzard Entertainment and based on the Warcraft series of RTS games first released in the mid 1990s. WoW expanded on the early Warcraft single player franchise and is now a vibrant multiplayer online world, where players may engage in roleplaying, PvE, PvP, dungeon instances, battlegrounds, arenas, and raids. WoW has received four different expansions so far, including The Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria, Warlords of Draenor, Legion, and the latest expansion Battle for Azeroth and is still going strong with another expansion in the pipeline.
Excess Potion of Accelerated Learning: Acquired in your Garrison (part of the Warlords of Draenor expansion), this gives you a 20-percent bonus to experience from killing monsters and finishing quests. It lasts one hour, but you can buy it multiple times and use it back-to-back. Alliance players buy it from Sergeant Crowler, horde players buy it from Sergeant Grimjaw. Does not work above level 99.
