Please note all charts and information below are for simple (single level) tech only and all the information assumes there are no defending troops home. The charts are not affected by morale - however they do assume each village is religious. Unless otherwise stated the information is based on no paladin weapons being used.
Rams Chart (simple tech)
Below you can find a chart that will show you how many rams it takes to kill off various levels of walls.
Catapults (simple tech)
The following information shows you how many catapults you will need to send to knock down ONE level of a building.
|Building Level||Cats Needed|
The following chart shows you how many catapults you would need to destroy a building from X level down to Y level. As you can see it is FAR more economical to send cats in waves!
As you can see, the most economical way to cat down a building would be to send in waves. For example, if you wanted to destroy a Level 20 HQ (which can only be downgraded to a level 1 building) you would send the following waves
(9, 8, 8, 7, 6, 6, 6, 5, 5, 4, 4, 4, 3, 3, 3, 3, 3, 2, 2) which is total 91 Cats - compared to the 312 Cats it would require if you were to send one command!
