Luck & Fortune Spheres is the actual grind.

I'm on my second run (first was one the PS2), have just past 200 hours and havs Celestial Weapons for Wakka, Auron, Rikku and Yuna. The stats are maxed for Wakka, Auron and Tidus, except for luck. Tidus has the highest amount and that's 70. I know 120 should be enough, but has anyone ever reached 255 for every character? For one character I'm sure it takes a few hours already.

After that some lightning bolts, chocobo's, butterflies.

After that Dark Shiva, Dark Bahamut, Dark Anima, Dark Magus Sisters, Dark Yojimbo and Penance.

Then I'm done right? Well I missed a few Al Bhed Primers, bit I don't be think I can pick those up later.
