The Ruler is an accessory purchased from the Goblin Tinkerer for 1 . It is helpful for intricate construction, as less trial and error is required for judging distances, symmetry, and achieving a desired block layout.

• Displays a line or L-shaped overlay showing x and y distance from the player to the mouse.
• Operates identically to the Mechanical Ruler .

The Ruler's effect is purely visual and is only visible to players who have it equipped or in their inventory.
