I need help competing the final step of the Exotic Weapon bounty for Thorn, which is level 26 moon phogoth the untamed, but we must not kill him until Xyor the un wed comes. She comes in the 3rd tomb ship and it doesn't matter if we kill phogoth as long as we survive until Xyor is killed. Any one willing to help please I'm on a ps4 lvl 29, gamer tag is caster1877. Thanks caster1877
