There’s a lot of content for players to plunder with this update, starting with the (re)introduction of the Ember Isle. This tougher level 50 zone includes 30 additional quests and many other activities to keep players busy at the level cap.
Also arriving with yesterday’s patch are the defensive-themed onslaughts, the Caduceus Rise dungeon, and Planar Attunement. This last feature is an ongoing character progression system that converts post-level 50 XP into advancement through several enhancement fields. The full patch notes are up as well and mention some of the class tweaks and general fixes that went into the game.
