Ruler



The Ruler is an accessory that causes a white grid overlay to display over the entire screen, revealing Terraria's tile layout more clearly (ie. the slots each individual block occupies, and where new blocks would fall if placed). This aides intricate construction, as less trial and error is involved in judging distances, symmetry, and achieving a desired block layout.

The Ruler's effect is purely visual and only affects the player who has it equipped.

It can be purchased from the Goblin Tinkerer for.
