Strategy

The arrow tower is most powerful against bats and spiders, but is decently effective against all the other monsters, excluding Bees, Golems, and Green Shields. Because of their large range and cheap build cost, these towers are very effective at the early waves of a level. The range becomes absolutely massive when at the purple level, and it begins to deal quite strong damage at the black level, so they can still be useful at the later waves if they are upgraded.
