I have only tried it once with a group of seasoned raiders. we did it 6 times correctly and the orbs never even put a dent on oryx. I'm kinda scared to waste my time again trying it. did it the way it is supposed to be done. no result, wiped, tried again... same thing. ogres four times, all orbs untouched with the assigned players, flinch oryx each time to repeat the process until there are 4 at each corner. detonate corresponding corners with correct players. nothing.
