The Mesa is a ninja sword in Final Fantasy XII. It is the upgraded version of the Orochi in the Zodiac versions, and the strongest ninja sword. It can inflict Poison on-hit. It can be used by the Shikari. As the ninja sword licenses are locked behind Quickening licenses, and the player can only unlock three Quickenings, it is not possible to use all ninja swords in one playthrough. If the player wants to use the Shikari to its best potential, it is advised to pick the license for Mesa and Yagyu Darkblade for 180 LP.
If the Shikari has another job that unlocks mystic armor, Yagyu Darkblade will greatly surpass Mesa in damage if the character wears Black Robes, becoming one of the best damage dealers.
Meṣa, or Mesha, is a month in Indian solar calendar. It corresponds to the zodiacal sign of Aries, and overlaps with about the second half of April and about the first half of May in the Gregorian calendar.
