In one line: your Office never waits for resources first. It waits for the Communications Center. Bring Comms up to your Office level before every upgrade, and Office 11 to 30 is ready the moment you can pay for it.
Office N needs Communications Center N − 1. Comms catches up first, every time.
Comms = your Office level → Office never stalls → speed-ups go where they count

The second building rotates
Besides Comms, each level from 11 asks for one more building in a fixed order: Bomber → Command Center (12 only) → Shieldbearer → Shooter → Bomber → Lab, then repeat. Know your next Office level → know which building to push this week.
Forticlad After Office 30
After 30 the Office moves to Forticlad levels. Each FC level has 5 stages, and each stage costs Forticlad Cores on every main building. From FC 5 → 6 you also need Advanced Forticlad Cores. Comms is still the gate.
| Step | Required buildings |
|---|---|
| 30 → FC 1 | Communications Center Lv 29, Shooter Barracks Lv 29 |
| FC 1 → FC 2 | Communications Center FC 1, Bomber Barracks FC 1 |
| FC 2 → FC 3 | Shieldbearer Barracks FC 2, Communications Center FC 2 |
| FC 3 → FC 4 | Shooter Barracks FC 3, Communications Center FC 3 |
| FC 4 → FC 5 | Bomber Barracks FC 4, Communications Center FC 4 |
| FC 5 → FC 6 | Shieldbearer Barracks FC 5, Communications Center FC 5 |
| FC 6 → FC 7 | Shooter Barracks FC 6, Communications Center FC 6 |
| FC 7 → FC 8 | Bomber Barracks FC 7, Communications Center FC 7 |
Core cost per stage (× 5 stages per level)
“Each barracks” means Shieldbearer, Bomber and Shooter each pay this.
| Step | Warden’s Office | Each barracks | Comms Center | Command Center | Medical Station | Level total |
|---|---|---|---|---|---|---|
| 30 → FC 1 | 250 FC | 130 FC | 50 FC | 50 FC | 50 FC | 3,950 FC |

FC 9 and FC 10 come from a newer table that lists 6 buildings (no Medical Station).
Your plan
- Comms first. Before you start an Office upgrade, Communications Center should already be at your current Office level.
- Read the rotation. Your next Office level tells you which barracks or Lab to upgrade this week.
- Save speed-ups for 21+. Office 21 → 30 is about 201 days of build time. Spend speed-ups on the Office and Comms, not on side buildings.
- Bank Forticlad Cores early. 30 → FC 8 takes 52,500 Cores and 1,620 Advanced. FC 9 and 10 add 16,100 and 3,335 more.
