I played with the team last night and it took a little bit an several wipes but we finally were able to beat him on hard. there is a trick, that I won't mention you can look it up online but using the strategy the relic holder needs to continuously break his shield every time he has a super because what this does is allows the team to shoot the first set of oracles and as soon as the relic older breaks the shield it interrupts him for spawing a next set of oracles and then everyone can proceed to do damage to him you can do this as fast as possible and you'll prevent him from getting to enrage mode Using this method we were very quickly able to beat him on hard
