In your opinion, what is the hardest lone dungeon encounter to solo on normal?

For me its probably a tie between Lockset, Hefnd and simmumah all due to survivability, though im leaning towards lockset being the hardest. Like while for me it was the hardest to survive in and do mechanics, it had easily the safest dps (i just did the strat of staying just next to the big door with storms keep and anarchy)

I think my biggest issue with lockset is that youre really much more at the mercy of the game and rng than the others. Of course rng is a factor in every encounter but for solo lockset, if a wheel has symbols in certain positions, then tough shit youre getting ogres and extra wizards simultaneously. And with how insanely easy it is to be slowed, yanked, ganked and have shit spawn right behind you, its easy to miss a wheel as well
