About this skill

Aegis Shields is an alliance skill that raises the protective field: it strengthens the shields of members’ fleets and defence. Strong shields take the first hit and absorb part of the damage, preserving ships and structures.

The skill is shared and funded from the alliance’s common treasury. The higher the level, the longer a defence holds in battle — a skill for those who value resilience.
