Amon Fusion Soul
Demon that appears in King Solomon's book of magic, Lemegeton. A violent, evil, and cruel soul. Its appearance signifies the end of the world.
Alice should keep using Arc whenever possible to balance out the damage dealt by Demon Rays and Atomic Dust. With Yuri, use either the strongest Fire fusion available, boost his attack, and keep hitting Amon with physical combos, or the strongest Light fusion available in case you need two healers. The third character in your party should support the other two, keeping their MP and SP from running out.
If one has defeated Amon and has the Destruction Stone, they will gain him as a fusion.
Amon is one of the 72 Goetic demons. He is also a Marquis of Hell, and appears as a wolf with a snake's tail. It is said that, in the command of a mage, he can take the shape of a man with a raven's head. He is said to tell all things of the future and the past. Some demonologists think his name is associated with the Egyptian god Amun. Other demons that appear in Shadow Hearts are Mammon, Gaap, Asmodeus, and Astaroth.
