Not only is it obscenely dark, as in if you dont have excellent eyesight, forget it, but the underpin mobs are bugged beyond comprehension. They randomly and sporadically phase in and out of shadow mode BUT they still attack while phased. This means the delve is essentially wasted on any challenging mode and it must be played below your skill level simply to avoid the 1 shots from out of phase mobs such as the “explosive ally” ones
This isnt the first time I have encountered this and thats why im here, because this shouldnt have made it through 1 pass, let alone how ever many weeks this has been a “feature” now
edit - after being 1 shot from full by an invisible “explosive ally” on a +11 i switched down to +8 and was still being wrecked down by over half my hp for several minutes by invisible explosive ally mobs that chased me all over the map, one of them literally died out of phase and i had to blink out of a pile of bombs that appears at my feet. Im not even sure how it died, brann wasnt doing much about them.
Surely it cant be hard to have 2 instances of underpin spawn locations with 1 set to “shadow” and 1 set to “normal” and “if shadow = true use ‘shadow’” or whatever
