Archer Tower

Overview
The Archer Tower is the first available active defense against enemies. It can be constructed after first building a Treasure Room.

The Archer Tower will automatically attack enemies that come within range. It shoots rapidly, dealing constant damage that is particularly effective against weaker targets such as Wolves and Vikings.

The Archer Tower must be built on a Wood Castle Block or Castle Block and gains increased range from elevation. It has a base range of 4 tiles and each level of elevation appears to give it an extra 0.65 tiles of range, for a maximum range of 10.5 tiles on a tower 10 blocks tall.
