Once your server reaches the Age of Forticlad (around Day 70) in Lands of Jail, you’ll be able to upgrade certain buildings beyond level 30. These buildings include:
- Warden Office
- All three Troop Barracks
- Communication Center
- Command Center
- Medical Station
These higher upgrades are called Forticlad Levels (or FC Levels). To upgrade to an FC level, you’ll need Forticlad Core as a special resource, along with the usual ones like Food, Wood, Steel, and Gasoline.
Each FC Level includes 5 sub-levels before moving to the next one.
For example, to upgrade the Warden Office to FC1, you’ll go through:
30-1 → 30-2 → 30-3 → 30-4 → FC1
