Pollux Core Fragment A

Pollux Core Fragment B
Location: Depths – Celestial Ice Prison
After defeating the Mud Gorger (with the group of moneys that spawn), head to the western side of the battle area to find a passage. Follow the path up, taking a left at the glowing blue trees to arrive at a rock ledge. Jump down the ledge following the rock formations to reach the core fragment.
Pollux Core Fragment C
Location: Depths – Celestial Ice Prison
From the mistle, take the eastern path leading to a narrow passage. When you emerge from the passage, you’ll be in a big cavern filled with lots of stalagmites (rock columns). Follow the left cavern wall to find a narrow opening on the left side. Head through the opening and follow the path forward to arrive at a rotten mistle. Jump down to a ledge below then drop down to a path. Head north, passing another rotten mistle, to find the core fragment in some white grass overlooking the starting area.
