I am disappointed with Deep Dungeon

It is true. You can tell by watching the yellow/white text next to your weapon as you level.

i.e. if your weapon is say level 21 and you are 43, it will be yellow. You gain a level and are 44, then now it's white - on the same floor. This DOESN'T mean you can level it at the floor though, it just means you can level the weapon on the appropriate floor.

that's just item level sync. you can still get rank ups when the stat is yellow, i was surprised but it happened to me.

my weapon level was 19, i was helping a friend run through it from the beginning, it was sync'd down to 17 cause my character level was only 34 or 35. opened up a silver chest and it went up to 20, even though it was still yellow and still sync'd down to 17.
