Tower

Defends: an archer of its own, with twice the reach, on a building with many hit points.

Once finished, a tower holds an archer of its own on its platform: 10 damage every 0.63 s, reach 280. The archer cannot be struck; it falls with the tower (1,200 hit points).

Alone, a tower holds off a raid of about six warriors, and falls to twelve in under half a minute.

Tip: A tower keeps its upkeep (15 gold/min) whatever it does: raise it where the rival comes, not everywhere.
