• You can start from the top vertical area of “The Mount Fay,” as shown in the image above.
• From here, run to your left until you come across a small vertical passway. Climb through this passage to reach the upper section on your left, and continue while dodging a trap until you reach another dead end.
• Use your wall-climbing ability to navigate through a vertical passage and reach the above area, which is The Slab.
• Once you are there, use the platforms to reach the left passage. Continue moving until you enter a snowy environment.
• Carefully jump down, and you will spot a passage just below the upper section from where you just jumped. Continue moving until you find a dead end, and next to it, another passage that leads downward.
• Simply go all the way to the ground and move left to find the Slab key attached to a metal chain.
• Hit the chain once to drop the key to the ground and take it. Be careful, as this area has two foes that can hinder your progress and inflict damage.
