So I know the 16 orb strategy and have done it multiple times on both characters but I heard there is another way you can do it. When oryx challenge first started I read in the forums that the challenge was to do it in 3 phases instead of 4. Correct me if I'm wrong but does that mean you can detonate the bombs 3 times or is the 16 orb strategy the only way to do it? Please help clear up confusion.
