This level begins with a cut scene that leads directly into a battle. Jager, your boss du jour is polished off pretty quickly. Just be sure to focus on him, and not the minions as long as he is alive more will arrive. Once you polish him off, head into Blackdale proper. At your first intersection turn left. There is nothing on the right for you currently. You will come to another intersection with 3 options, left, right and straight. Explore both left and right for important component like stone, copper and oil. Go straight last over the stone bridge you will find another path on the right. Explore it for a treasure chest that is pretty full. You will encounter a battle here, but it won’t be too difficult. Back on the straight path you will encounter a sapphire path. Keep going straight and eventually your path will widen. Open the chest and save before going any further. You will find a Marsh Dig site, which makes Mr. Diggs happy. This is his food, and increases his capacity. Once you have the morsel head on. Soon you will trigger a cut scene and begin your last battle in this town.
Your opponent is surprisingly strong and shoots fire. He can damage all of your unions at the same time. So be ready to heal often. Beating this Idol can take some time and be deeply frustrating. Just remember that protecting your own union is paramount. Guest unions can die without consequences, but if your unions bite the big one your game will end.
