Hit it with one big warrior wave, at least 50k warriors, then keep hitting with at least 20k warriors each wave until u capture it. It would be helpful to have one free spot in your feasting hall, usually the heroes get captured much sooner than the NPC. Then you can stop conquering it. lol. Just make sure you hit it lots and lots times and have that free spot to accept the hero.
