Survival Rooms are found in Clockwork Tunnels. They work like a Danger Room, but an infinite amount of waves pop up. The brave Knights who manage to get past this room get Crowns and other rewards. In order to get said rewards you may notice a number at the top of the screen, it shows how many waves you have left to get through. Once you do so. The fight goes on instead of immediately stopping. However, to make things easier to stop, monsters here drop only 1-pip hearts, in tier 2, same as tier 1, in tier 3, 2-pip hearts. You may question how you know what enemies will appear and what element they may wield. It is quite simple. It depends on what Clockwork Tunnel you're on. Example, you'll find Oilers in a Blast Furnace: Slimeway Survival Room, of course. Once everyone in your party is down, you respawn with half your max HP and the prize gate and entrance gate goes down, along with every enemy dying at the same time. The design of the Survival room always has traps. But it will always be different. There could be spikes, freeze trap, shock trap, poison trap, and fire traps depending on what Clockwork Tunnel you're on.
