老いたドワーフの魂:
Because the exterior of this lock...is the super metal Tolecium...it is virtually invicible...to physical attack... However, it is...very sensitive to attribute energy...If it is continually exposed to...energy with nature attributes...its surface will be temporarily weakened... Below 1/10, the different energy intensities...between the exterior...and the interior...may cause a strong...extruding effect.
If you are lucky...you can take advantage of that effect...to enter the Tower of Naia...
Keep listening.
