I've engaged in the AP trick a few times, although for it to work to maximum potential I will need to increase the kill count for some of the characters and unlock the Comrade Overdrive charge for Yuna.
Then you're doing it wrong. It should only take about 20 minutes to get enough AP to fill the board per person. And you don't have to worry about stat maxing. Just running everyone around the board and filling in most of the blank nodes is good enough.
I like many other players find Kimahri useless, despite the fact that he is easier to mould into any job class that the player see's fit to than any of the other characters. I guess I'm not keen on Blue Mages, given that the majority of their skills become redundant in later stages of the games.
His best use is as a second thief.
I'm not even going to attempt to dodge 200 bolts of lightning in order to get Lulu's Celestial weapon and I don't think I'll be getting Wakka's because I am useless where Blitzball is concerned so it looks like I'll have to build him one.
No. A weapon with BDL is not the same as a celestial weapon. There is a HUGE difference in damage output potential. Besides, it costs a lot of Dark matter which are a pain to grind for and the ones you do get are better served someplace else.
Wakka's is probably the easiest to get. There is a really simple team you can make that should be unbeatable. There's also a trick you can do at save spheres to ensure you play the least number of games necessary. Getting Wakka's weapon and Overdrive are a must. He'll be your biggest damage dealer.
And just bite the bullet and do the lightning dodging. Honestly, I could never understand why people find it so difficult. Heck, I always just garbed it the first time I went through there. I've always found Chocobo racing and butterflies to be way more difficult.
Especially because I always use Lulu when I didn't have to have Yuna. I got really good at her OD and could consistently get 8-12 charges.
What I do is lay my hand flat with the analog stick in the center of my palm and then rotate my arm at the shoulder. I can do it much faster and accurately than just using my thumbs.
Does anyone know where I can get decent armour drops that contain skills such as Auto-Phoenix, Break HP Limit or Auto-Haste? I already have one for Wakka that has Auto-Regen and Break HP Limit on it, courtesy of Dark Valefor, but it's a real gamble relying on chance drops from the Dark Aeons (who are also incredibly fast and difficult.
Most of that stuff can only be obtained from Dark Aeons or the harder MA monsters. The drops are really rare and usually you'll just get one with two or three slots.
It's best to just make them yourself. In the long-run (although a lot more tedious) it will be faster. You can buy 4-sloters from Wantz provided you talked to him and bought stuff every time. I DON"T think you have to have had done the side-quest where you give his brother money, but I can't remember.
Other wise, you can get them from drops from the monsters in Sin or Omega ruins. I forget which ones specifically.
In the long run it's best to just make them yourself.
For doing the hard stuff armors should look like this:
Wakka/Tidus:
Auto Haste
Ribbon
Auto Protect
Auto Phoenix
for Lulu and Yuna swap ribbon for Auto-Potion. You'll want to in-turn keep their attack stats as low as possible to negate confuse. This is a bitter harder to finagle with Yuna, of course.
Don't even bother with break HP limit. It's a complete waste.
