The Magma Rock is a Key Item in Xenoblade Chronicles. It is required for the Story Quest The Magma Rock, and is obtained by defeating the Conflagrant Raxeal in the Lava Cave on Valak Mountain. The Magma Rock can be used to melt a thick ice wall at several locations on Valak Mountain.
Locations of Thick Ice Walls
- The door to Ose Tower in Harict Chapel (the objective of the The Magma Rock).
- A tunnel northeast of Zokhed Pass which leads to Serik Waterfall and the Apis Lair.
- The long, narrow passage south of the Nopon Camp that leads to a wind Ether Crystal deposit.
- The ice cave northeast of the Great Glacier, where a Nopon Researcher is imprisoned and gives the quest Bad Timing.
