About this skill

Crystal Synthesis is an alliance skill that raises crystal mining on members’ mines. Crystal is needed for fleet, defence and science, so extra output accelerates both war and research.

The skill is shared and funded from the alliance’s common treasury. The higher the level, the more crystal per hour — a reliable boost for a tech-minded alliance.
