When you are in the Forbidden Land near the pink healing thing, there will be two paths. Go forward and you will end up fighting the Grand Jewel Boss. To prepare for the battle, go right instead of forward. You will fight a third Virage Boss. He is not that difficult, and is the weakest of all Virages. Winning will get you 6,000g and 12,000 experience points. Also, if you go to the Phantom Ship you can get the Ultimate Wargod Amulet in a chest. However you must learn the combination. Explore the ship and you will eventually enter a room with five or six ghosts. Go up to them and press [X]. Each ghost will say a number. You must use these numbers to get the correct combination for the chest. At first, you will only get Healing Fog and other items. Eventually, you will get the Ultimate Wargod Amulet. Note: The combination numbers change each time. Also, you only have five chances to get the correct combination. If you fail, the bones on the ground will will form into skeletons that you will have to fight.
