I'm trying to reach Orin Grimcaster to defeat him but on one of the floors i died and then came back once i had my health and mana back up. When i got back i did not have to fight on the previous floors i just had to go back to the floor that i was on. The problem is, once i defeated that floor the gate didn't open and i cant get through so i don't know what to do because i don't want to have to do the dungeon from the start again
