Raegwyn, the well-known World of Warcraft solo player, took down the 40 million hit points of Supreme Lord Kazzak, a powerful raid boss designed for a 40-man group, sitting on top of Tanaan Jungle. Since Kazzak is a world boss in World of Warcraft, random people could come and attack it as well. Raegwyn finally completed this task after more than 20 tries.
In World of Warcraft history, there are some easy world bosses such as Nalak and August Celestials. In patch 5.4, almost all tanks can solo Nalak, however, not all world bosses in Mists of Pandaria are piece of cake. Do you remember the epic wipes of Oondasta?
