Gedonia 2, early access: episode 16, extreme difficulty rogue 2

I'm a little over leveled for the enemies I'm up against at this point. I still have some difficulty with enemies meandering around when I'm trying to sneak up and eviscerate an enemy standing a little close to at least one other enemy for a little splash damage.

Extreme difficulty's upscaling of enemies' quality and quantity only matters if you're not playing aggressively enough and if your damage output per target isn't high enough to kill most or all enemies before they can start to fight back. In the case of a close range playstyle it's simply a matter of the "initiator" phase of combat where you can eliminate one or more enemies within 10 seconds of the start of engagement.
