Bishamon O Flute
There are two places in there game where a very strange man hanging from the ceiling by his feet stares at you and ignores you. Later in the game, after you use the Evil Plate and open the door, he will talk to you. The man will now take you (whenever desired), to the Dark Realm. In the Dark Realm, kill monsters until two portals open; one to go up and one to go down. Keep going down to the last level (9th or 10th) while collecting all the items en route. Open the box on the deepest level to get the Bishamon O flute. Keep the flute just before the last fight with the Demon King. It is needed to get the Bishamon Sword.
In the Demon Realm (just after you destroy the Ultimate Creation) is a save mirror and three doors. Go to the door that resembles an iron gate. It will not open at first. Use the Bishimon O flute on it and enter. Go to the Bishimon Sword jutting out of the Skull Demon wall object and take it. It is more powerful than all three of your weapons put together, and it has speed. The sword also has an unlimited supply of magic.
If you are low on health at the end of the game before facing the Boss go to the entrance of the keep for some battles. By now they should be easy -- just absorb the souls to raise your health
How to beat Marcellus
At the end of the game you should have all weapons and orbs at the maximum. When fighting Marcellus again, kick him and use the Thunder Orb's magic. For some reason, this is stronger than his other attacks.
