+## Usage Patterns
+
+Slot into a Villa or Officium covering mines and quarries to dramatically reduce both workforce requirements and maintenance costs. The -80% maintenance reduction makes this specialist extremely valuable for cost optimization of mining operations.
+
+## Common Pitfalls
+
+Misplaced radius leads to zero value; only affects mines and quarries within the Villa or Officium range.
