Trivia

Prior to the release of the Tombs of Amascut, and with it, the Osmumten's fang, the Corporeal Beast had a damage cap of 50. This was removed to allow players to use the fang to its full power against the Corporeal beast, since it is one of few weapons that doesn't have its damage halved against it.
