About this skill
Metal Extraction is an alliance skill that raises metal mining on every member’s mines. Metal is the base resource of any construction and fleet, so a boost to its output speeds up growth on all fronts.
The skill is shared and funded from the alliance’s common treasury. The higher the level, the more metal flows in each hour — a fundamental boost for a growing alliance.
