Game Mechanics: City of Mist: Abnormal Black Reaver trains

[isidian]

The main cause is 2nd floor PCs agroing mobs that train through the locked door at the moat. I have also seen yo-yoing behavior from levitating PCs camping the ramp.

But you are correct that it is possible to push mobs through the wall at the stairwell of the gazebo. They'll jump to the 2nd floor and in all likelihood, you and the rest of the zone will be unhappy with the result.
