Ballista Tower

Overview
The Ballista Tower can be constructed after first building the Chamber of War.

The Ballista Tower will automatically attack enemies that come within range. It has more range and does significantly more damage per hit than the Archer Tower, but has poor target tracking speed and a long reload time. It is ideal for killing Ogres and Dragons, although it has some trouble turning fast enough to target the latter.

Just like the Archer Tower, the Ballista Tower must be built on a Wood Castle Block or Castle Block and gains increased range from elevation. It has a base range of 7 tiles and each level of elevation appears to give it an extra 1.3 tiles of range, for a maximum range of 20 tiles on a tower 10 blocks tall.
