Limestone Properties, Ancient Pyramids & Structural Routing

Limestone forms the impenetrable architectural backbone of ancient desert pyramids and subterranean temple ruins. With a listed durability of HP 40 and complete immunity to all mining tools and thermal heat, Limestone serves as a permanent environmental barrier for factory logistics.

Property	Specification	Automation & Engineering Rule
Structural Durability	HP 40	Retains static integrity; impervious to drills, lasers, and blast weapons.
Tool Resistance	Impervious to All Tools	Cannot be mined or cleared; routing around formations is strictly required.
Thermal Immunity	Burnable: No / Meltable: No	Unaffected by contact with Lava or open flames. Ideal natural heat break.
Occurrence	Pyramids & Subterranean Ruin Walls	Encloses sacred artifact puzzle chambers across the arid desert biome.

💡 Desert Pyramid Navigation Rule

Because Limestone structures cannot be breached by any early-game or late-game tools, never attempt to tunnel straight through pyramid walls. Instead, locate natural entrance corridors or route elevated conveyor bridges across the exterior dunes to bypass solid Limestone foundations.
