As the title. The Balthazar event chain is bugged on Northern Shiver Peaks
The chain didn’t properly end last night and the karma vendor never toggled to “vendor” mode after the risen priest of Balth was killed.
This morning the NPCs are invincible (health regens instantly) and beset by a horde of infinitely spawning risen. There is a sufficient number of them for culling of enemy mobs to occur.
