The Castle Siege dungeon arrives, requiring a new currency found in the castle area. The lobby system has been reworked, every player can now open a portal, not just the host.
Key changes: resetting mastery points now costs 1 key, totems are real targetable units, enemies check line of sight for skills, modifiers drain stacks gradually, and a new HUD scale slider is available. Breakable objects can drop stamina potions, and health/stamina potions now apply buff effects.
