You can also get Magic Points only in the Cult of Kefka's Tower. Had to equip Wall Rings at such a low level though.

Haven't posted in a while so.

It's possible to upgrade Odin into Raiden. Avoid doing so if you figure out how. The only way to increase your speed stat is through Odin.

The only thing we can do now is tell you what the FAQ tells you. That you can steal Ribbon's from Bracosaurs and get their dropped Economizers.

I steal Thunder Shields to turn into Genji Shields in the Collesseum. You can easily beat the game at a low to mid level with some spells and bought equipment.

I don't think it merits an in depth response. Hope you enjoyed the game. I'm sure others can help you out too.
