It's annoying enough as it is to get to floor 100 solo, but when you're literally screwed left and right from RNG in Palace, such as a never ending wave of Chimera, and you get KO counts that PREVENT you from getting your achievement because you can only get the bloody thing by dying past Floor 50/100, but you can't get past 100 unless you have no deaths at all.

This does not add 'replayablility' SE, this is just a dumb as hell lockout. Other achievements we get RIGHT AWAY, this is the only thing I see that doesn't give them until we die.

And I'm not going to be redoing any of this solo again if I'm screwed over due to RNG bs killing me by spawning 4+ wondering monsters all in a line.
