Upgrade Your Archers
As you eliminate the enemies, you will gain EXPs. Use them to upgrade your troop. In later levels, you will need more power during a battle since the attacks get harder. When you get enough experience points, you will see an arrow pointing up at your men.
Click on which archers you want to upgrade. They will level up in this way, and their damage power will increase. There are five upgrade levels, meaning five unique archers. Each comes with its special powers.
Strong Walls and Fighters
You can also enhance your fortress's walls to make them more resistant to attacks. In the "Shop" section, acquire the "Strong Wall," which costs 2000 coins and makes your tower more durable.
On the other hand, you have the option to upgrade your fighter's features here, too. You can see those five archers side by side. Acquiring upgrades will increase their damage rate and critical hit percentage.
