Have 2 titans in the middle running bubbles with touch of malice. One use weapons bubble the other use blessing. Let them focus on ogres. Everyone on platforms snipes their knights, meet back up in the middle after relic runner has relic. Titans will also kill 4th knight. Stagger oryx, rinse and repeat til there are 4 stacks of 4 orbs. Have your platform guys run and detonate their orbs, one of the titans will detonate the 4th stack. Do a 4 second countdown after oryx is staggered before detonating (allows everyone time to make it to their stack). Have the 2 guys in the middle (relic runner and 2nd titan) keep shooting oryx in the chest while the bombs are being detonated.
