bro what
I should note that the assassin's dagger killcount is bugged; every tiem you pass 1k kills, it starts incrementing by a factor of 10 instead of just 1 (so 10 per kill at 1k, 100 per kill at 2k, etc...) at least i think that's what it's doing. the actual kill count is the +damage it's getting.
and yeah, i got lucky early by getting the dagger and shield spirit to keep things rolling. had plenty of room for lucky rings as well, so i found more golden whetstones. Also at one point hit a wheel-game with golden whetstones on it and blew through 1k gold trying to get as many as I could. think i got 6 or so off of it?
anyways, still playing this same save, i'm up past 600 floors now. I also hit another wheel game with whetstones, though i only got 4 out of it this time. I'll probably post another screenshot later :D
