This huge turtle evolved in mythril mines, and while its attack pattern is the same as a land turtle's. Its P. Atk. and P. Def. are elevated by the power of mythril ore.
The Mythril Shell is an enemy in Bravely Default. It will occasionally Default, followed up by a Spin Attack, which deals damage that ignores defense. It will also use Reflection Angle, which can now be dispelled with White Magic. As such, launching a full-scale magic offensive, especially of the Water element, and dispelling its Reflection Angle when it uses it will make victory easy.
[view·edit·purge]The word "mythril" or "mithril" is a metal found in many fantasy worlds. It was originally introduced by the fantasy writings of J. R. R. Tolkien, being present in his Middle-earth. It resembles silver but is stronger than steel, and much lighter in weight than either. The author first wrote of it in The Lord of the Rings, and it is retrospectively mentioned in the third, revised edition of The Hobbit in 1966. In the first 1937 edition, the mail shirt given to Bilbo is described as being made of "silvered steel". The name mithril comes from two words in Sindarin—mith, meaning "grey" or "mist", and ril meaning "glitter".
