Grimoire (item)

Grimoires are recurring items in Final Fantasy. The most notable use of the term Grimoire comes from the Ivalice collection. First mentioned in Vagrant Story, then in Final Fantasy Tactics Advance, the Gran Grimoire is a powerful tomb of magic. Grimoires may also be purchased in Final Fantasy XII, entitling the party to increased benefits of different sorts.

Grimoires, at this point, do not exist in Final Fantasy XI, but their presence will be felt shortly in the upcoming expansion Wings of the Goddess. Grimoires will be used, primarily, by Scholars not so much as weapons but in order to take offensive and defensive stances for casting magic.

Etymology
Grimoire comes from old French "grammaire," a word that is also the root of the modern English word "grammar." Grammaire refers to something that relates to letters.
