Mount Muspel is a volcanic area, covered in mineshafts and mine railways. Many Fire Type Coromon live here.
There is a secret area (X) within the second basement floor of the mine, which contains a Smart Gem. This area is only accessible with the Tremor module.
Toruga and its evolutions can be found on a small special area (S) just outside the Titan's chamber at BF3.
This theme plays when the player is on Mount Muspel. (For Mobile Users, click here)
Puzzle Solutions & Strategies
In Mount Muspel the player rides minecarts in order to cross gaps and lava pits to reach the next floor. To ride a minecart simply interact with the cart by pressing the (Use) button. The Push module will be automatically equipped when riding a minecart, while on it the player must use the module against the end of the railway track in order to push the minecart and gain movement. To exit, simply press the (Use) button again while facing any direction other than the end of the railway. To reset any of the puzzles, exit the floor or use a LuxRecall.
