I couldn't miss the chance to practice my drawing!
Frost is a Ninjutsu spell for Edge exclusive to the Nintendo DS version. It is the final Ninjutsu spell, and once learned at level 60, Edge can pay 20 MP to unleash moderate Ice damage on all enemies.
Frost returns again as a Ninjutsu spell, and can only be used by Edge and Izayoi. It functions the same way it does in Final Fantasy IV. Edge learns it at level 45, while Izayoi learns it at level 42.
The Ninja learns three different levels of Hyoton abilities. Hyoton: Ichi is learned at Level 15, Hyoton: Ni at Level 40, and Hyoton: San at Level 75. Each Hyoton ability does ice-elemental damage and lowers the target's resistance to fire damage. Both effects increase in efficiency with the level of the Hyoton ability used.
Hyoton is a Ninjutsu available to Ninjas at Level 35. Its combination is Ten→Jin or Chi→Jin. Hyoton deals 140 ice-elemental damage to a target, binding the target for 15 seconds and cancelling auto-attacks.
In PvP, Hyoton replaces Jugulate after executing Three Mudra. It delivers ice-elemental damage to a target with a potency of 1,000 and binds the target for 4 seconds. It also resets the Shukuchi recast timer.
