How do I upgrade Towers?
Each Tower can be upgraded individually to improve its performance and unlock abilities. Upgrading a tower improves the following stats:
- Damage: The amount of damage the tower deals to creeps.
- Health: The amount of damage a tower can receive before being destroyed.
- Range: The range at which the tower is able to attack creeps.
Infantry Towers function slightly differently. Instead of increased Range, they receive upgrades to the Unit Health of individual Dwarves. This allows them to survive longer in combat and increases their effectiveness at stalling Creeps!
Each Tower has abilities that are unlocked at ranks 3 and 6. These abilities will trigger on their own once unlocked. Some abilities happen on a cool-down and others are triggered randomly when they hit enemy Creeps.
