The Staircase is a consumable mining supply item used to instantly create a ladder that leads down one level in The Mines or Skull Cavern. It cannot be placed on level 0 or 120 of the mines. Staircases cannot be stacked in inventory or chests.

Staircases work just like the game-supplied down-ladders. Each one works only for one use. If you leave the mine or return to a higher level and look for one you placed earlier, you will find that it is gone. In addition, once a staircase has been placed, it cannot be picked up again, even if it has not been used.

If you do not have enough Stone to craft a staircase, you can buy Stones from Robin at the Carpenter's Shop. 99 Stones at 20g each = 1,980g per staircase.

Use

Staircases can be used to pass through mine levels at any time (one level per staircase). You can use as many as you have or can make, repeatedly. But making them can prove to be a heavy use of resources, so it is usually best to reserve them for occasions where there is enough need to justify the expense. They are an assist to situations of greater challenge or difficulty. These tend to present themselves more often in later stages of the game.

Tips

• Use a staircase to evade one or more monster fights. Some mine levels can be especially challenging. Consider upgrading your weapon instead, though.
• Use staircases in the Skull Cavern to return multiple times to the same level, to give you repeated chances for or quantities of valuable items, like Iridium Ore and Prismatic Shards.
