What Should I Upgrade Next?

After your next HQ prerequisites are handled, don't upgrade buildings randomly.

Ask:

What's currently holding my account back?

Then upgrade the building that solves that problem.

Formation I

Upgrade Formation I when strengthening your Main Troop is the priority.

Each level provides:

+1% ATK
+1% DEF

to that Troop only.

Other Formation buildings affect their respective Troops.

Main Troop Camp

Upgrade the Camp associated with your primary troop type when unlocking the next troop tier is your bottleneck.

The three Camps are:

• Assaulter Camp
• Shooter Camp
• Rider Camp

Keep the others on the required HQ progression path unless you actively use those troop types.

Military Center

Upgrade the Military Center when troop capacity is restricting your training.

Problem: Not enough troop capacity
Solution: Military Center

Hospital

Upgrade your Hospital before periods of repeated fighting when wounded capacity is becoming a problem.

Problem: Wounded capacity too low
Solution: Hospital

Warehouse

Upgrade your Warehouse when you regularly hold more resources than it can protect—especially before being offline for longer periods.

Resource Protection Tip

Keep unused resource packs unopened until you actually need them.

Resources sitting safely inside packs don't need to be opened just because you received them.

City Walls & Alliance Center

Upgrade City Walls and the Alliance Center when they're required for your next HQ upgrade.

They don't need to match your Headquarters level at every stage.

Shelter Upgrade Priority Checklist

When you're unsure what to build next, use this order:

1. Check your next HQ requirement
2. Upgrade the Laboratory/prerequisite building
3. Keep essential resource production moving
4. Push Shooter stages while builders are busy
5. Upgrade your Main Formation/Camp when needed
6. Upgrade Military Center if troop capacity is limiting you
7. Upgrade Hospital if wounded capacity is limiting you
8. Upgrade Warehouse if resource protection is becoming a problem
9. Avoid random upgrades that don't solve a current need

The Simple Rule

HQ first. Prerequisites second. Everything else according to what your account needs.
