Season of Mastery Patch 1.14.3.42770 PTR Datamined New Spells & Items

The latest patch for Classic Season of Mastery is now available for testing on the Classic PTR, which had some development notes posted by Aggrend. As of right now, players are able to test the Temple of Ahn'Qiraj, which includes an overhauled Prophet Skeram encounter and a difficulty selector for the remaining raid.

The next phase of Season of Mastery will be Phase 5, which features Ahn'Qiraj and the War Effort.

That also means players will likely need to do the The Scepter of the Shifting Sands quest chain to open the gates of Ahn'Qiraj. As of right now, the only fight that has seen significant updates is the Prophet Skeram encounter.
