Castlevania Circle Of The Moon Cheats

Use DSS in Battle Arena:
In the Battle Arena, equip a good DSS Summon Combo (for example, Uranus + Cockatrice). In the pause menu, select "Items", then "Use", and use a "Mind High" (not a "Mind Restore" -- they can work, but you will need to be extremely fast). Immediately after exiting the pause menu, press your DSS button. When your character is done casting, press Down, Forward, Up, Attack. If done fast enough, you should have pulled off a summon in the Battle Arena.
