As Long as you do not complete a Final Kill on the diffifulty, you can constantly change the difficulty to anything +1 of the previous map's completion difficulty (Can not do Easy> Hard, Must at least be Medium to change to hard mode, but reducing Hard> Anything is OK); thus also resetting the Boss HP bar at any time.
