Where to find it

It is in a chest inside the Raya Lucaria Crystal Tunnel in Liurnia of the Lakes. Take the first elevator down after the Site of Grace, cross a wooden beam, and look in the second room on the right, where two Marionette Soldiers stand guard without paying much attention.

Item description & lore

Glintstone miners used these knives as tools to cut glintstone free from rock, which is why a faint magic still clings to the blade.

Notes & tips

  • Unusually for a weapon upgraded with regular Smithing Stones, it cannot be buffed or have its affinity changed.
  • Its critical multiplier is lower than most daggers, so it is not a strong choice for backstabs and ripostes.
