About this skill

Lunar Defense Protocol is an alliance skill that guards moons: it raises the chance to save a member’s moon from destruction during an enemy Death Star attack. A moon is a valuable strategic object, and keeping it is worth a lot.

The skill is shared across the alliance and funded from the common treasury. The higher the level, the more firmly your moons hold — a skill for those who prize their lunar bases.
