Taking a tour to Remiem Temple Belgemine awaits Yuna to challenge her to an all out Aeon Duel. All Stats of Belgemine's Aeons are Unknown. First you select the Aeon you wish to face then select your own in battle. Most of her Aeons should go down in a single hit if you Summon Anima. However since you cannot have 2 of the same Aeon in the battle at once your best bet is to call forth Bahamut when Belgemine is using Anima. After each battle Belgemine gives Yuna an award. One being a key item needed to obtain the Magus Sisters. If you've got the Blossom Crown from the Calm Lands Arena then avoid Belgemine and destroy the barrier blocking the door in the far end of the Temple. Note: Belgemine will not let you face Yojimbo, Anima or the Magus Sisters if you haven't already obtained them yourself. Yojimbo can be obtained in the Cavern of the Stolen Fayth. Anima can be obtained at Baaj Temple. Magus Sisters can be obtained at Remiem Temple. After all Aeons are defeated Yuna is given the option to Send Belgemine. Send her and you'll be able to upgrade Yuna's Celestrial Weapon. Hint: You can choose not to send Belgemine and carry on battling her Aeons. After each rematch you'll get something like 10 Power Spheres or 8 Mana Spheres. Great for increasing your Aeon's Stats. Feel free to Comment, Rate and/or Subscribe. Enjoy.
