The guards will only attack players in PvP mode or Challenge mode. Otherwise, they will only be examinable. Pit rooms cannot be exited unless the guardian is dead or challenge mode is off, however this will not affect the house owner. Pit guardians do not give any experience and do not count towards a Slayer task. A crystal saw may not be used to boost your level to buy the pit guards, though a Sculpting chisel and visible boosts will work.
When built, the dungeon automatically comes with four Oak doors. The player does not directly build these, and the player also cannot remove them, which means the player cannot build Steel-plated doors or Marble doors in their place. When in construction mode, the doors are ghosted out, which makes them appear like buildable hotspots even though they are not.
The same occurs in regular mode, but only if there is no pit monster placed in the room.
