I've tried it near a Qactar Stone (single strike) and walked for about 45 min., got hit, went to the Travel Agency, saw that I'd only done 145!!!!! I then found a two-strike area... it's just sooo fast!

I just decided against bothering with it. I already have Rikku's, Tidus', Yuna's and Auron's. Tidus does 99,999 damage whenever he hits, and has Auto-Haste and Quick Hit and Blitz Ace. I'm trying to get there with the others, it's just taking me awhile. I only use those 4 characters.

I just don't think it's worth the hassle.
