Castlevania: Circle of the Moon Cheats
Have lots of hearts, plenty of Crucifixes, and both the Jupiter and Golem DSS cards. Use the Jupiter and Golem card combination for the Invincibility Duration X4. Attack him with the whip for a while and when he hurts you start launching crucifix. He won't be able to hurt you due to the invincibility duration. This lets you do a lot of damage to him without him doing it to you.
