I don't like via invinito its to hard when it gets harder and the bosses are guit tough and the only time i go down there is to get the sphere to do den of woe every time. i defeated chac first time and black elemenal and concherer. chac and concherer were quite tough but black elementl was easy whith moogle beam. i normally bribe paragone but i leveled up to 99 and whoped his ass lol. then i beat trema. then i completed the game.
