Scathe is the strongest Black Magick spell in all of Final Fantasy XII. It deals non-elemental damage to enemies in range and has the maximum effect capacity, which means no other spell or Technick can be performed simultaneously. Scathe costs 18,100 gil to buy, and is only available from the Baknamy merchant in the Necrohol of Nabudis after completing the events at the Pharos. It costs 70 MP to cast, and requires the Black Magick 8 License, costing 120 LP, to use.
In the International Zodiac Job System version, Scathe cannot be bought. It is a Level 13 Black Magick and costs 165 LP to use. The spell can be found relatively early in the game, in a chest in Lhusu Mines Staging Shaft, and consumes 70 MP each cast. It can be acquired as soon as the Antlion Elite Mark is completed and the player has the Site 11 Key from Phon Coast. It can only be used by the Black Mage job class.
Despite its animation sequence, the effect area of Scathe is not exactly a straight line shooting from the caster as in Final Fantasy Tactics A2, but a circular area just like other area Magick in Final Fantasy XII. The beam does not usually point straight in front of the caster, but usually positions itself to hit most enemies in range.
Scathe appears in Final Fantasy XIV: A Realm Reborn as a Thaumaturge ability available after completing the "Threat of Superiority" Thaumaturge guild quest. The ability deals non-elemental damage with a potency of 100 to a single enemy. The ability has no cast time or cooldown. The potency has a 20% chance of doubling once the player has learned the Enhanced Scathe trait at level 24.
