How Do I Get the Holy Sword in "Symphony of the Night"?by Joshua Benjamin ; Updated September 22, 2017
The "Castlevania" series of games has a long-standing tradition of sending heroes into castles to kill monsters. The original "Castlevania" protagonist was armed only with a whip, but later games increase the arsenal to include axes, daggers and swords, among other weapons. The Holy Sword in "Castlevania: Symphony of the Night" is one of the more useful weapons in the game, as it has a burst attack and does holy damage to the hosts of undead creatures you have to face.
Travel to the Colosseum level.
Equip your jump boots or your flight power and travel upwards and to the left until you encounter a room filled with Blade Masters.
Kill the Blade Masters, and then destroy the ceiling just after the second pillar in the room.
Fly or jump up into the newly-created opening to enter a secret room containing the Holy Sword.
