Dumbest Event ever created perhaps - Grand Inquisitor

How is it supposed to beat it using Relic 5 characters is out of my mind. It is incredibly hard and frustrating, no fun at all just pure pay to win and upgrade your character to higher Relic. Relic Delta doesn't event make it easy. Just frustrated. I spend 10 hours and still can't beat the event. Using God tiers mods and still same luck
