Metamorphose is the attack used by Ragnarok when summoned. Ragnarok has a chance to turn an enemy into one of four items with varying rates of success. Some enemies have a higher chance of being turned into one item than the others. For example, of the four items a Veil Dancer can be turned into, three of them are Potions and the fourth is Miracle Shoes, thus while there are only two items the Dancer can become, there is only a 25% chance of that item being Miracle Shoes.
