Ancient Belt

The Ancient Belt is a mystical belt in Castlevania: Aria of Sorrow that improves many statistics, with an emphasis on defensive stats (+7 Defense, +5 Constitution, +1 Strength, +1 Attack, +1 Luck. This is in contrast to the weaker Black Belt, which emphasizes offensive stats.  Although it is equivalent in total power to Satan's Ring (which has the same amount of Defense, but whose other statistics are evenly distributed to +2 each and trades Luck for Intelligence), it is more common and worth much less gold (750 vs 5,000).  The Ancient Belt was replaced with the Power Belt in Castlevania: Dawn of Sorrow.
