Hope this guide will help to successfully capture Historic Hero.
First go to inn and click Folk Hearsay and find hero you want to capture. Remember that hero you can capture only if its shown on Barbarian City, not in Flat or other player city. After see the info that he/she at Barbarian city do not enquire. Go to Statistic, Hero and input that Historic Hero name to see if the Hero already owned by other players or not. If he/she already owned by other player, you had to find another Historic Hero. If no one own it then you can go back to inn and enquire that Historic Hero. You need 10c for enquire the Historic. When enquire is done you will receive that Historic Hero picture on Item, Quest section and you will got mail in Report, Other section about coordinate of that Historic Hero was atm.
After had his picture and the coordinate you can tele to near that coordinate (the best way is use adv tele) and start hit that coordinate. Do not, i repeat do not scout the coordinate coz it will make Historic Hero move to other coordinate. Make sure you had free slot Hero at your feasting hall then send 4 or 5 waves of attack at the coordinate. Sometime only at first wave you can capture the Historic Hero but sometime you need a lot more waves before you can capture it. Remember don't conquer the coord. If that coordinate loy near 0 and you still haven't capture the Hero then you should stop for an hour before start the attack again.
PS: You also may click Accept Task after do enquire, it will give some bonus item if you success capture the Hero
If there anything i miss here please add the info please, thanks .
