After defeating Del Lago, you can now navigate the lake freely. Head towards the Quarry. This area is infested with Ganados, including some with dynamite. Be cautious and use the environment to your advantage. There's a Merchant here as well. Your goal is to find the Dynamite to clear a blocked path. The Dynamite is located in a small shed at the far end of the Quarry. After acquiring it, use it to blow up the rockslide blocking the path to the Fish Farm. The Fish Farm is a waterlogged area with several Ganados, including some in the water. Use your knife or shotgun to deal with them. Explore thoroughly for resources and treasures, including a Spinel in a hidden barrel.
