The pattern imprinted on the floor by Sky Dragon Slash
Ryudo performing Sky Dragon Slash.
This is Ryudo's signature and most powerful move. It is the fourth move learned and becomes available after the second battle with Melfice. It hits all enemies and is very effective, but expensive: 99 SP (SP consumption may be reduced with the help of some accessories or the Granasaber).
Melfice has his own variation of this move: the Demon Horde Slash, which produces a blue version of the Sky Dragon Slash Pattern.
