Burial Chamber boss needs altered

Having soul eater isn't necessary.

Why not?

Would it be better if it had 15 invulnerability phases like most new bosses have?

The main problem isn't the boss with souleater. The main problem is this map literally forces you to burst boss. I think the main idea was something like "use single-target skill this time" but in the end it's simply a dps check.

It's bad game design. Bosses reseting after the player died is good game design, it's keeps players from ripping through the content, but high amounts of life reg is just ridiculous and offensive towards the player. Mighty fine tanky zdps builds should be a thing in the build meta and not burst the boss down in seconds with a single target skill or retry the map...

And why would it spawn it's own mobs on top of that? Put some mobs there so it can blow up the player with corpse explode once or twice for nostalgia sake but then that should be it, not some insane loop if you can't kill it very fast.
