My group found a counter for the teleporting ogre, if it's only 1 teleporting or if 2 happen to teleport really closely to the other. If it teleports to the middle, then use the death singers platforms as your hiding spot(ala no knight strat) During the final damage phase, usually, you have 4 people detonate the bombs, and 2 stay behind to Dps Oryx. Have the 5th person (eg, not the relic runner) detonate the 1 odd bomb, while trying to Dps Oryx from the odd bomb location. We managed to pull it off
