Plumbum

Plumbum (graphite) is a dense mineral resource used for military units and structural reinforcement. It is found in Graphite Deposits — dark, rocky formations on the map.

Gathering

• Harvested by Prospectors
• Each trip yields 3 Plumbum
• Graphite Deposits contain 300 Plumbum before depletion
• Deposits do not regenerate

Uses

Plumbum is required for:

• Advanced combat units (Proteges, Pikemen)
• Building construction (Pencilcore Press, Parapet, Patternworks)
• Defensive upgrades
• Refining into Pencilcore at the Pencilcore Press

Strategy

Plumbum is scarcer than Paper and does not regenerate, making deposit control critical. Scout for Graphite Deposits early and secure them before your opponent. Prioritize Plumbum efficiency — don’t overspend on units that require it unless you have a secure supply. In long games, Plumbum scarcity often determines the winner.
