Aim for useful training milestones

Castle progress and troop unlocks are different

The Castle supports your account’s progression. The levels above are the recorded

Barracks

gates. Castle 30 alone does not unlock T10.

Build the path you actually need

Follow the next Castle gate

Check the exact prerequisite buildings before committing resources to the next level.

Keep research moving

Choose research that supports your next goal; include prerequisites in other trees.

Choose one eligible branch

An OR requirement accepts one listed alternative. It does not require all three faction buildings.

Keep useful work running

Avoid an upgrade plan that leaves every queue idle because the next coin bill is unaffordable.

The T10 unlock checklist

Castle 30

Meet the construction prerequisites.

Scholar Tower 30

Use an eligible Tower I or II branch.

Barracks 30

Prepare the training gate.

Soldier X

Complete its research prerequisites.

These are required milestones, not a fixed order for all four. Construction and research can be prepared alongside each other.

Choose the next upgrade for your account

A larger Castle does not replace a functional squad, stocked queues or useful daily rewards. Meet required levels first, then catch up on other buildings according to the bottleneck you actually have.
