Successfully beating bosses in any of Legion’s raid encounters now nets players with another chance of getting a Legendary Item. This is critically important because upon killing any world boss you’ll have a chance to receive a Legendary Item.
Whichever world boss happens to spawn will be the target of a world quest that will last a few days ensuring that all players have a chance to tackle the boss. Legion offers you the chance to kill one of eleven world bosses every week. Upon completion, you’ll be rewarded with a loot box containing gold, order resources, or most importantly, a potential Legendary.
