[quote]Hello everyone, My raid group and I are having some difficulties defeating Oryx on hard. We have completed Normal mode countless times, but can't find the luck for HM. We use the no knight method, and feel that 8/10 times we detonate all four bombs. The only time that we can deal damage to Oryx is when someone dies, which is just a wipe anyway. Our first thought was that we were taking too long to detonate the orbs, but when we do it flawlessly we still have problems. We also think it may be connection issues, but we can do it no problem on normal. Any thoughts will be appreciated, we'd like to figure this out before the Oryx challenge dissapears. Thanks guardians![/quote] Edit: thanks to the suggestions here we figured it out! We were not keeping his chest "open" while detonating. We tooka that part of the fight for granted the first times through I guess. Thank you everyone who gave a suggestion!
