Teak trapdoor

A Teak trapdoor can be built in the trapdoor hotspot of the Throne Room in a player-owned house. It requires 78 Construction and 5 teak planks to build. When built, it earns the player 450 experience. This can be used, in turn, to build an Oubliette. If you have Challenge mode on, this trapdoor leads down but not up.
