Mechanical Ruler

Mechanic acquisition and grid measurement overlay

Purchased from the Mechanic for 1 gold coin after liberating her from the Dungeon depths. The Mechanical Ruler projects a translucent measuring grid across the screen, displaying tile increments and alignment markers outward from the player character. This grid allows builders to align symmetrical walls, verify room dimensions for town housing, and plan boss arena spacing without manual block counting. Placing campfires, heart lanterns, and sunflowers at measured intervals becomes simple and exact.

Inventory operation and Grand Design integration

The coordinate display operates directly from the inventory or vanity slots and can be toggled on or off via the interface icon beside the inventory. At a Tinkerer's Workshop, the Mechanical Ruler combines with a Ruler, colored wrenches, and a Wire Cutter to forge The Grand Design, creating a consolidated wiring and structural toolkit. Engineers keep it on hand to troubleshoot intricate teleporter networks and automated mob farms.

Trivia

• The measurement grid toggle can be switched off in the inventory screen if the grid lines clutter combat visibility.
• Unlike the basic Ruler, the Mechanical Ruler projects an extensive two-dimensional block grid across the screen.
