A marble spiral staircase can be built in the staircase hotspot of the Dungeon, Quest Hall, and Skill Hall in a player-owned house. When building spiral staircases additional sets of materials are needed - one set for the base floor, and one for each floor you wish to access. Marble spirals require 97 Construction, 10 teak planks, and 7 marble blocks to build each floor. When built, each floor earns the player 4,400 experience.

Note that when used, a spiral staircase will always ask you whether you wish to go up or down, when you click on it. Note that spiral staircases can connect to all three floors. Materials are needed for each floor the staircase connects to.

The other complications associated with staircases involve adding rooms, or changing the staircase.

A staircase added to a Skill Hall on the regular level will prompt you to build it "Up" or "Down". When building an "Up" staircase, then attempting to climb the staircase, the construction interface will ask if you want to add a room at the top of the staircase. The rooms available at the top are either a Quest Hall or a Skill Hall. If you build a "Down" staircase, you have an additional option of building a Dungeon room downstairs.
