A dungeon entrance can be built in the centrepiece space of the garden and formal garden in a player-owned house. It requires 70 Construction to build and when built, it gives 500 experience.
It is, as the name suggests, used as an entrance to a player's dungeon. It can only be used to access the dungeon if the player has a stairway conjunction built below the garden. It can be accessed during challenge mode, which can be triggered by activating a lever in a throne room.
It should be noted that if you are looking to build a cheaper entrance into the dungeons your options are:
- Stairs can be built in a Dungeon to connect to a Skill or Quest Hall above.
- A trapdoor can be built in a throne room connecting to an oubliette room underneath. This assumes you already have a throne room built.
