Then, in the area just beyond the second Marcellus boss fight, use the Ocarina on the bone door here to open it. Then head inside and claim the prize, a sword with unlimited magic which will kill any non-boss character in a single swipe. | |
Secret - Ogre Armor | |
| Battle through the Dark Realm that has ten levels. (Not to be mistaken with the Dark Realm that contains twenty levels) Upon completion of the tenth level, open the chest to get the ''Secret Key''. Take the key to the area with the Red Minotaur boss fight. Use the key on the large door marked with a plus sign to enter an area that leads to the Ogre Tower. Once inside the Ogre Tower, enter the portal in the middle of the room. Defeat the enemies on each of the 6 floors, to unseal the next portal. When you return to the main level of the tower, give your souls to the glowing statue to unlock the corresponding portal. Repeat this process for the remaining statues. On the 5th and final portal, you must face a boss on the final floor. Defeat him to gain the ''Ogre Armor'' | |
