Flooded Crater

The Flooded Crater is the Mortar boss room.

It can be accessed in two locations after killing Mortar.

The main entrance is found on the fourth floor of Dungeon with a boss icon on the map.

Since it is a boss room no Pilfers can spawn inside. This makes it an ideal location for using.

After the boss has been killed it the room will have a ladder allowing for the player to exit.
