Once you get the Azure Flute (Key to Arcues), go to a very familliar place that you players never thought you would visit twice...The Spear Pillar. Once you walk two steps onto it your flute will begin to create music. Once the stairs appear walk up them, a level 80 Arceus is waiting for you. SAVE! Battle him and catch him at all costs. Bring a good stock of Ultra Balls or a Master Ball. Once you catch him give him one of the plates you've racked up over the hours, he'll change types and colour. He is the ultimate fighting partner. Mine knows Psychic, Flamethrower, Recover, and Dragon Pulse, but that's personal preferance. Each moves has at least 90 power and accuracy, he's the best.
