about lv.4 keys, you can bribe a chimera brain in the calm lands 245,000gil for a maximum of 4, minimum of 2. as they appear in 2's thats a max of 8 in one battle they usually appear behind the agency.

btw, it is possible to get most things without having to fight dark aeons, the only things it is impossible to get are in besaid meaning u hav to fight DV, but he's the easiest

to earn blitz ace really fast, go to bikanel dessert. set tidu's overdrive to slayer and use energy rain. the beuty of this is that if u hav triple overdrive (celestial weapon) it instantly fills his OD agen, for the next battle go to bikanel because enemies appear in 2's or 3's more often than not, which is enough to fill his OD.

u can also use bikanel to lv up if u can't get don tonberry cos cactuars (valey of the cactuars) give lots of AP. with triple AP its possible to get bout 120,000 AP in one battle, this isn't as much as the don but its easier. dont worry bout dark ifrit, u hav to go out of ur way to find him (towards the ruins of home)

in blitzball, after scoring one goal more than the opposition just get the ball then sit in ur net, n the other team will leave u alone

is that all?
