Odin's Grimoire (オーディンの黒書 Ōdin no kurosho, lit. Odin's Black Book) is a Tome that is introduced in Fire Emblem Fates. Eponymously named after the Dark Mage Odin, Odin's Grimoire conjures a crimson bolt of fell energy to impale a selected enemy target when used in battle.

Odin's Grimoire can be considered a harder-hitting, less consistent variant of the Mjölnir tome. Though it possesses the higher might, Odin's Grimoire has lower hit and critical hit rates than Mjölnir. Additionally, it cannot perform follow-up attacks, and it reduces the user's critical evade rate by 20 points whenever it is equipped—Mjölnir does not inhibit its user in either of these ways. However, Odin's Grimoire does not lower Avoid by 10 points, unlike Mjolnir.

  • The burst of energy fired from Odin's Grimoire in Fates is identical to Siegfried's long range attack.
    • It is also similar to Awakening's Thoron, but black with red lightning.
  • In Heroes, the blade summoned in the animation greatly resembles Mystletainn.
