Cliff Crusher

Cliff Crusher is a mining building that extracts Sand from terrain tiles. Its extraction throughput varies by tile type; measured per-tile rates in available data show base rates ranging from 0.27/sec up to 1.09/sec, with corresponding maximum rates (presumably accounting for multiple adjacent tiles or stacking) from 0.54/sec up to 2.18/sec. The Cliff Crusher requires an aggregate input throughput of 11/sec to operate at full facility-level capacity.

Cliff Crushers are restricted in which wall and environmental tiles they can mine. They cannot extract Sand from Arkyic Walls, Graphitic Walls, or Crystalline Stone Walls. They are also unable to harvest Sand from most environmental walls on the Serpulo tileset. These exclusions mean Cliff Crushers are ineffective on certain late-game or special-resource surfaces and should not be relied on as a universal terrain digger.

There are no booster items or modifier buildings available to increase the Cliff Crusher’s extraction rates; this contrasts with some other mining or production buildings that accept booster upgrades. Because boosters are not supported, throughput improvements must come from placing multiple Cliff Crushers, optimizing belt/transport throughput to meet the stated 11/sec input requirement, or selecting more productive tile types.

Practical notes and operational points:

• Expect per-tile extraction performance to vary significantly by tile; plan layouts so Cliff Crushers operate on the most productive tiles accessible to your base.
• Ensure downstream transport (conveyor, router, or buffer) can handle the aggregate output; the listed maximum rates indicate a single Crusher can produce bursts up to the higher values if fed appropriately.
• Do not attempt to place Cliff Crushers on Arkyic, Graphitic, or Crystalline Stone Walls (or many Serpulo environmental walls) to obtain Sand; those tile types will not yield Sand to the building.
• Because there are no dedicated boosters, scaling output is primarily a matter of increasing building count and improving logistics rather than slotting upgrade items.

Use Cliff Crushers where natural Sand deposits are present and accessible, and avoid relying on them for resource extraction from specialized or fortified wall tiles.
