So as you guys probably know or maybe not know, there is 3 kinds of rooms in beaver and bat dungeons,
1. Clear the room with no additional spawn which unlocks the next door
2. Killing "X" of spawning mobs will unlock the door.
3. Clearing the room AT THE SAME TIME before next monster spawns unlocks the door.
Rooms 1 and 2 are perfectly fine but getting the 3rd room kind basically makes u go out of the dungeon and look for another one, even doing bat dungeons on w10 with "titan" stats was like that, that kind room is just stupid, it's suuuper unbalanced to the other 2 rooms and makes the entire experience really really boring stat-check where you have to kill 5-6 monsters at the same time before the next one spawns. I think it would be better to get rid of that kind of room, add something else or just leave these 2 rooms.
