Village level info

Each village has 5 different tiers. Every time you upgrade it, it generates units faster, gets more defense, and has a higher unit capacity. The cost and duration it takes to upgrade villages also increase as the level increases:

The higher the level, the more defense the village will have and the faster it will produce units, making it easier to defend. It is impossible to upgrade to a  tier 5 village, however some maps allow you to start with a tier 5 village.

Tip

Upgrading villages also increases your morale. If you upgrade earlier than your opponent, you can have a morale advantage. After a failed attack, if safe, upgrading can help even the morale scale.
