Unlock Requirements and Why This Branch Matters
Siege to Seize opens before the deepest late-game branches, but it is still a serious badge commitment. It works best as a deliberate aggressive path, not as a random detour.
- Unlock requirement: 40% Military Strategies.
- 100% Siege to Seize unlocks Field Research.
- This branch is usually stronger after your key Peace Shield value is already secured.
If you are using badges mainly for safer PvP value, Peace Shield often deserves priority before a full Siege to Seize push.
