That's true, Jessa, but I bet you beat 10k next tower, and if you hold on to those medals you'll get the extra 2500 you missed on top by the tower after. Numbers of KH is just a factor of how long you've been playing (unless you whale). You will make up that power gap pretty quickly at the start.
Unlucky, Slashey. Happens to everybody (or rather it happens all the time to me, and now I know it happens to you too). Thanks for the sheet, it helped no end, hot mess or not. I dropped 1 key on floor 15, then basically took 2 keys per floor, finishing on 18 with 1-17 complete, all missions. That's good for me, rank 165 at the end. So much better than my performance on Skill Check kun.
