Mini Dungeon Limit, theres a limit? xD

I believe as many times as you want per day. I think the reason why the timer is there is so people can't afk in a map when they're not training.

i can confirm that you can enter as many times per day as you want though you can only stay in for max of an hr at a time

there is a "glitch" thats nice with the current ones that if you leave and reenter you go back to the exact same map you left instead of entering a random one (the map doesn't reset when you leave, though the timer does)
