“Powerful on the defense, a Castle also allows you to appoint a powerful General to lead your army!”
- The Fort (Castle) acts like a Tower when your town is under attack. Additionally, you can recruit a General who will act as a defender.
- Upgrading the Castle increases its hitpoints and damage, as well as unlocks additional Generals and/or allows you to upgrade your Generals further.
- When you deactivate a General, the cost is not refunded if you trained a second General with oil.
- The Fort starts out as the Castle from level 1 to level 2 and finally becomes the Fort at level 3.
- After the 5.8 balance update, the defending Generals will spawn with 70% hitpoints if the Fort (Castle) is destroyed before they go out to defend,
