- New Dungeon: End Time

- In this new 5-player Heroic dungeon, adventurers travel back 10,000 years in a brazen attempt to retrieve the Dragon Soul.
- New Dungeon: Hour of Twilight

- New Raid: Dragon Soul
- Players have the opportunity to take the fight to Wyrmrest Temple and beyond, assisting Thrall and the Dragon Aspects as they seek to bring an end to the Black Dragonflight once and for all. 10- and 25-person raids will get to take on Deathwing himself, with three levels of difficulty to consider and epic gear to claim.

- New Legendary Item: Fangs of the Father
- The most deadly and experienced rogues will play a central role in the fate of the world the rogue’s way: by manipulating key events from the shadows. Players will travel across continents to accomplish crucial missions of reconnaissance, burglary, infiltration and, of course, assassination. Rogues who succeed will receive a paired set of daggers that will become increasingly lethal as their bearer progresses along the legendary quest. At the height of their strength, they will be imbued with the vile essence of the Old Gods, as well as the maddened fury of the Black Dragonflight -- bestowing great power upon their bearer. These powers include a stacking increase to Agility which builds until dark wings unfurl from the rogue’s back, removing the combo point cost and increasing damage of finishing moves for a short time. In addition, the wings which can be spread on command (with no combat benefit) to slow a rapid descent, allowing the rogue to slowly fall to the ground… or enact a little death from above!
