Things You'll Need
Instructions
Scout the targeted level ten NPC by clicking on the NPC and selecting "scout." Send at least one scout. Continue to scout the NPC until you find a hero that is level 20 or lower. Once you have found an NPC with a level of 20 or lower do not scout it again as this will assign a random hero to the NPC.
Attack your targeted NPC with your top level hero with the following combination of troops. 92,400 archers, 1,900 scouts, 1,900 warriors, 1,900 workers and 1,900 transports.
Attack your targeted NPC with 40,000 warriors immediately after your first attack lands. Be sure to send a hero with every attack. Immediately after this attack send 30,000 warriors and a hero and do not wait for the other attack to land. Immediately after this attack send 30,000 warriors and a hero and do not wait for the other attack to land. Send all of your remaining heroes to attack the NPC with 20,000 warriors for each attack.
Wait for your top level hero and your archers to return. Attack the NPC with 70,000 archers and 10,000 warriors and your top level hero. Attack the NPC with 40,000 warriors and a hero after the first attack has landed. Send all of your remaining heroes to attack the NPC with 20,000 warriors and a hero for each attack.
Repeat step four until you have conquered the NPC. Keep in mind that the loyalty of the NPC will go up in between attacks so you should minimize time between attacks where applicable.
