i noticed that if you managed to defeat oriales at the Hount Highlands battle, you get the weapon "final Sword" (28 atk) for leon. and by defeat i mean HP to 0.
my strategy was two poison drops (or was it 3?), one small hit and then one big hit like an Energy Breaker.
i dunno if this happen in the first encounter with him but i doubt the characters would be strong enough by then.
Another special item not said in the FAQ (not surprising) is the Mystery Dress for Dorothy. outside the Arbour pavillion should be a man with red hair : ask him about "Tastes in Clothes" and he'll give it to you. --- Giovanni : hahaha Im the caid of my shoes and i control every toe-nail in it.
