How are you actually supposed to beat the obsession boss?
For context i beat it with a team of Vestal Runaway Crusader Leper because I wanted to try out an Monarch Leper. Run went pretty well apart from letting loathing consume twice, got really good trinkets but against the boss I definitely lucked out by the Vestal surviving so many luminence deaths door hits and popping a resolute, the plan quickly turned into keep her alive as long as possible so Leper and Crusader could chunk away at its healthbar but she still ate like 7 deaths door hits, even with all that luck we still got down to just Leper who survived a few of his own deaths door hits and his own resolute. Point being, my success is not really replicatable and would like a more concrete strategy in the future, or at least a general guide towards the right answer. Is it just supposed to be a dps test?, are you meant to spread the damage around with blocks?, debuff it so it doesnt do such devastating damage? Also what's the point of the first phase with the smaller eyes?
TL:DR got lucky on the Obsession boss fight and looking for a general idea on proper strategy for any future runs
