The table below is correct if the two villages have around the same population. If your village is bigger they will not be as effective.
The following table shows the minimum number of catapults needed to completely destroy a building of a certain level. as well as how many catapult it would take to lower a building of a certain level by 1 level. Assume no walls, palace, defenders or stonemason upgrades, nor upgrades in the attacker Blacksmith and population of the village equal to 550. Keep in mind that a single catapult will always die in an attack, so where it says 1, there must be additional accompanying troops for this to work. A star next to a number means that it is impossible to lower that level of building by only one level, the given number will lower it by 2.
|Building Level||Whole Building||One Level|
Note: The cranny goes up to level 10, trapper and stonemason to level 20. These buildings cannot be targeted directly, but can be hit with random strikes. Bakery, Flour Mill, Brickyard, Iron Foundry, Sawmill go up to level 5
All other buildings and resource fields go up to level 20.
If catapults or trebuchets are instructed to aim at a building or field that doesn't exist, they will instead fire on a random target.
This table lists the number of rams necessary to completely destroy a wall of a given type an level, given that all rams survive the attack and the rams do not have any Blacksmith upgrades.
|Wall Level||Rams To Destroy|
|Earth Wall||Palisade||City Wall|
