I laughed when I was sent in the air by one mob and occulted by another. Frozen in air Well, it was funny till it started happening again and again....but it doesn't really make the instance that tough. Still pretty much solo-able.
There's also a special spot in 1k. 132, 862 (walk a few steps forward. at some point it works) Does the same thing. plunges you into the air and teleports you to the platforms xD the end of each platform does the same thing. have fun
This is added to the game by the PWI GMs, I think its more common to happen if you do not complete the pavilions fully, which causes the mobs to reel you in, push you away, push you up.. etc..
