This morning we were treated to the revelation of Journey to Un'Goro's Shaman quest, Unite the Murlocs, which took everyone by surprise. Many had presumed it would be focused on the new Elemental minions given the fact that the class is one of three that is more focused on the tribe.
While that may have saddened some, Hearthpwn has revealed Kalimos, Primal Lord, an extremely powerful Elemental and the Shaman legendary for Un'Goro.
If you played an Elemental during the previous turn, you'll be prompted to select one of four invocations - Fire, Water, Earth, or Air - which all offer solutions to different problems.
Low on health? Snap up that Invocation of Water. Need to clear the board? Cast Invocation of Air.
