In the PAL version that I have, yes rubah you're correct, 99 Dark Matters for Ribbon. I did this, BREAK HP/MP LIMIT and auto pheonix on a shield and a ring, but saved over the game by accident, terrible, terrible feeling.

Months and months later, I'm replaying, Tidus is just starting to hit 99'999, and I have BREAK HP and MP on his Endless Road. This time, instead of going for Ribbon on two armors, I'm going to have BREAK DAMAGE LIMIT on my capture weapon, it'd make it so easy, yet exceedinly boring. But still easy!
