The Stone Thrower is the artillery unit of the Bronze Age. The unit has a horrendously low attack, low defense, and low speed, but is has the longest attack range in the Bronze Age. It receives an attack bonus on hills. It is effective against the Heavy Unit Class. Unable to move through rock, water, and swamps.
Stone Throwers can also be strong against enemies when in high numbers. When attacking armies with 1-4 heavy units troops, using 3-4 Stone Throwers is recommended. Concentrate all of the attack on one of the heavy units at a time until they are all defeated. This will hopefully destroy all of the heavy units before they can attack, making it easier for the rest of your army. After the Bronze Age, using stone throwers is strongly discouraged. In fact, not building the Stone Thrower Camp at all is a good idea.
Stone Throwers are quite inefficient and useless, though they can be a nuisance to the enemy when used in large numbers. It has the lowest attack in the game, making it only adequately effective against other stone throwers and also the Slinger. It does very little damage to Spearfighters and warriors even with the attack bonus, and the later should be attacked with Slingers or Archers. It is only good when a player is competing the BA PVP Tournament (e.g. using 4 Stone throwers and 4 rogues). But using Spearfighters is a much better idea overall.
