About this skill
Construction Protocol is an alliance skill that streamlines the building sites: it reduces building construction time for every member. Structures go up faster, and the base grows without idling in queues.
The skill is shared across the alliance and funded from the common treasury. The higher the level, the swifter colony development — a skill for those who hurry their growth.
