"The first boss is a giant ice elemental.
The second and third boss are both minions of the Old gods featuring scary, and horrible tentacles. The second boss is a Faceless One general named Warlord Zon’ozz.
The fourth boss is located at the Eye of Eternity. A female shaman, featuring some totem combat mechanics.
The fifth boss is a monstrous Twilight dragon that you had never seen before. It is so big that it cannot land. Players will have to fight in the air.
The sixth boss is the general of the Twilight’s Hammer.
Players will pursue Deathwing by riding a gunship as he tries to flee. The Twilight’s Hammer will try to intercept the players, and an imposing tauren general of Twilight’s Hammer will be the main antagonist of this encounter.
The seventh and eight encounter is against Deathwing.
The seventh encounter is fighting on Deathwing’s back. Other dragons and aspects will assist the players along the way. Deathwing will try to roll over, dive as he tries to get rid of the players. Thrall and players must rip Deathwing’s armor off, and eventually made him crash into the Maelstrom.
The last encounter has many phases. The location is the Maelstrom. The first phase is moving around the isles around the Maelstrom. Players will have to fight his claws, wings, tail alone and the tentacles. Traveling around the isles is similar to the fight in the Throne of the Four Winds.
During the second phase, the four dragon aspects will arrive and use their specific abilities to assist players to battle Deathwing. Players need to decide which aspect’s help. For example, Nodzormu can create a time-warp field to slow down Deathwing’s molten missile attack. Alexstrasza can annihilate the small tentacles Deathwing calls upon. Ysera and Kalecgos both have their own abilities. And, Thrall will use the artifact, the Dragon Soul, to join the battle. For further phases, no more spoilers!"
