Kill them one by one
As they do not equip with devastating skills, your team can combat them without Mortal online gold. The important factor is to pull them separately and kill them one by one. Your team should split up and fight so that you can increase your chance of survival. A warrior could solo one if he use Disarm as much as possible to cut the damage that may happen. There will be nothing really worth mentioning. Our team often kills Tack first and then Pooch dies immediately afterwards.
