[PS2] Kingdom Hearts 2

I found that a great place to level both the Wisdom and Master forms is in the Timeless River world. I just make my lap around the pier and those areas and then through each of the doors with whatever form I'm leveling.. There's plenty of weak enemies to kill with Wisdom(and I found I kill around 70 or so guys every run) and the cars and fat heartless drop lots of drive orbs for the Master form...just a suggestion in case this wasn't mentioned..

Jam it back in, in the dark.

Hey I'm trying to get all the Orichalcum pluses and I'm missing two. One I know is a reward for beating a certain cup I think I've yet to unlock but the other comes from collecting every type of material. Unfortunately I'm missing one..and I'm not sure what it is or where to get it so perhaps someone could help me?

On the list of materials in the synthesis screen its right above Dense Stone I believe and the icon is a black crystal lookin thing.....I can get a more specific location next time I play but in case anyone knows what/where it is it'd be appreciated =)

There's nowhere I can't reach.
