If you have 3-4 Chief and want to conquer a village which is far away (about 14:00 hrs attack time of catapults). Then you must follow this strategy. (If you have 5 or more Chiefs just clear target village’s troop and Send all the chiefs they will do the job. Don’t forget to destroy his residence first). You must have town-hall in at least one of the village. You need to have a Great Celebration before Chiefing the target. (This increase your chief’s efficiency).
