Grand Delta

Grand Delta (known as GrandTrain in the original SNES releases) is a Blue Magic ability in Final Fantasy VI, learned by Strago Magus as one of his Lores. The spell deals strong non-elemental magic damage to all enemies. It can only be learned from Hidon during the battle with him at Ebot's Rock, or in the Advance port, from Omega Weapon.

Grand Delta's spell power is 84, or a little more than half the spell power of Ultima. All the same, it is Strago's strongest offensive Lore. It costs 64 MP to cast.

Trine has a similar animation to Grand Delta, and in the original Super NES release, was called Train. This may have influenced Grand Delta being renamed GrandTrain.
