Now Live! Temple Ahn’Qiraj, Ruins of Ahn’Qiraj, and Nightmare Grove

news.blizzard.com:

Face your fears when you gather your allies to confront the Old God, C’thun in Ahn’Qiraj and the Dragons of Nightmare in the Nightmare Grove, plus more in Season of Discovery Phase 6.

At the completion of the 48-hour war, the Ruins of Ahn’Qiraj (a 10+ player raid dungeon) and the Temple of Ahn’Qiraj (a 20+ player raid dungeon) opens, allowing players access to the dangers and treasures within. All bosses within these raid dungeons are now mandatory to defeat to complete the raid dungeon.

Inside the Ruins of Ahn’Qiraj and Temple of Ahn’Qiraj players will need to decide how far they want to push their skill to earn additional rewards with an optional new system we’re calling “Descent into Madness.”  These additional rewards can be earned on top of the guaranteed loot dropped by the bosses within these two raid dungeons. To opt in, players will need to choose to take part before the encounter with the first boss in each raid.

Players who choose to test their abilities against the increased difficulty of each boss are provided with a limited number of attempts to succeed in earning these bonus rewards. If the raid group succeeds, they’ll be rewarded with a bonus chest which provides additional items for the raid. Players can choose to loot the bonus chest for the additional rewards or can opt to continue to the next boss. Opting in to the next boss will destroy the previous chest and allow the raid to try for a new chest with additional items in it after the next boss. There are check points in place as you progress through the raid dungeon so that should you fail at some point, you will still be awarded a minimum amount of bonus loot if you’ve reached one of those checkpoints.

The choice between more rewards to hand out to your team and facing increasing difficulty will be entirely up to the raid group to decide. It's important to note that rewards are in addition to those that can be earned from the regular boss loot but aren't more powerful. Compared to previous phases
