We did it with three friends and three random. Three 29/Three 30's. We missed one oracle on the last shield break, and that was it. Myself and two 29's stayed in the bottom to clear rear oracles and three stayed at the spawn. Only one of us had a gjallahorn. Not all had maxed weapons. It took a damn long time, but is doable. It felt like such a victory compared to hard previously, because everyone wanted to push him.
