Gameplay[]
Supply Run[]
The first thing you need to do is to climb the cliff side to the top. Take care of the scorpions and run down the gorge. Cutscene then plays for a bit. Run along the cliff side. Careful not to fall down. After a bit, there's a rocky bridge you can cross. Before you do, press the switch and watch the enemies down get crushed by the boulders. Cross the rocky bridge, then take out the orcs, archers and a single wizard. Climb up the ladders, deal with even more enemies. There's a wooden bridge, but however, it gets destroyed when you try to cross it. So climb up some rocks, and jump across some rocky platforms. Then jump from rope to rope onto the other side of the cliff side. Continue the path. Then a Dark Avatar will appear. Deal with him and continue down the path to the Sanctuary of Ideyr.
Sanctuary of Ideyr[]

Right off the bat, you'll notice a couple of orcs fighting some guardians. You can either watch them fight each other and take out the victors, or interfere with the battle. Continue to the path, and you'll see the Sanctuary. However, it is closed off. Go left, shoot the gong and find a flooded passageway underwater, just underneath the stream. Swim straight (to where the Air bubbles are), then turn right, then left. Continue the path to find an Ancient gold key guarded by several Yuki-Onnas. Backtrack to where you went underwater and enter unlock the door to the side of the Sanctuary. Watch out for the heads that spit out several fireballs. At the end, there is a switch that will open up the Sanctuary. When inside you will need to lit up two fire pits located to your left and to your right. after going through the passage on the left, you just need to climb the wall to get to the pit. For the passage on the right, you enter a big room with a slope on the floor. There you'll need to look up and shoot the gong to raise the stairs to get to the fire pit. Once both fire pits are lit up, enter the newly open door. Then you need to destroy three statues. Once all of them are destroyed, head back to where the big statue is as another door just opened up. Watch out for the Serpent God waiting for you here. Thankfully she won't use her accursed head attack. Once you take her down, pick up the Sacred Ash, then go back to the beginning of the map. Another Serpent God is waiting for you here. After dealing with her, put the Sacred Ashes into the pit, and the mystical creature will appear.
Release the Sciu-Crak[]

In this map, you are up against the Kraken. You can damage the Kraken only by using Yo's charged attack. He can be charged either by attacking the tentacles, or by slashing the nearby Octabrains. Once the Kraken dies, the mission will end.
Secrets[]

- In the hallway with the heads shooting fireballs, go to the wall on the left. A hidden door on the other side of the room will open. However, it will only be open for a limited time, so quickly go in there as fast as possible once it opens. If you get in the room just in time, you'll get a platinum amulet.
