this is my first forum thing so I'm probably going to mess it up
here goes nothing
the mercurial set is rather bad compared to anything else so I suggest adding ASI universal low (speed, get it?) and either buff msi as a whole, or put msi med on it. that seems fair for a boss item, now what would SK be without paywalls? lets hav it as msi low at lvl 1, at lvl 5 add the ASI low, and at lvl 10 put msi med. the 4* will get asi low at 10, possibly evening it out a bit?
if ur sick of radiants ignore this
I suggest putting radiant fire crystals at depth 24 and up, and so OOO can't backfire it with abysmally low chances,(I currently get no roads at 26) remove ALL shining fire crystals from depth 26 and up, for a fair chance (possibly only put this in arcade, it needs it)
alternatively (for arcade) put the same amount of boxes (red) as the final part of the gauntlet at the core, that only contain drops if u joined from at least d23 and below (I found 23 is safe because people will whine if its emberlight and will cheat the system if its lower)
remove whisker requirement for non black kat stuff, even pay for better gear is a bit wrong (that's all for that)
for the mixmaster, during the cake event make it come from the 4* storm driver (see? no need for extra weapon coding) and make it require a multiple of 1 new material that is bought with cake slices (I said multiple because cakes expire, so many of a cheap mat is more fair than a few expensive ones)
that is all
I kno I'm not typing with good wording grammar or whatever, its hard to avoid autocorrect
edit:fixed some things that got auto corrected
I didn't expect it to actually post the first try, my phone isn't very cooperative
