I read somewhere (I think it was Wikipedia) that having your arm in that fashion was a sign of loss of a mentor or friend. And since in FFX Auron's two closest friends were killed it may be because of that (But then again I can't remember if his arm was like that before they fought Sin)
I find it to be a great challenging game (despite being stuck on Ahriman at the moment >.<) although what the above two guys have said are right the characters were lacking quite a bit. The storyline is alright and the graphics are spectacular but I still have FFX at the top with characters and storyline (Auron Pwns all).
I say stuff like that all the time. Just tell her in a serious tone that you aren't and that you're just being silly. Also assure her that drugs are bad and that'd you'd never take them. Ever. Unless they're medicimal.
Anyway, using learn and jump is the key along with rumbling rose. But more important than them is guard and reflect. Ok when he starts and puts his wind shield he will then use either the attack where he stabs with all 6 or slashes with them. If you guard the stab run forward and hit triangle repeatedly. DON'T USE JUMP NOW.
If he uses the slash then guard that and use learn. When you get nine, use them up and use one combo on him with the keyblade. He'll either start stabbing and slashing again or start jumping. To dodge the jumps wait for a little swirl of wind to appear behind you and then jump forward (don't do anything else but jump) and after you have use learn repeatedly.
Don't use jump until he starts shooting wind balls at you and when he does hit him and combo him. Immediatly fall to the ground and guard because he will start going crazy with his spears. If you guard them repeadtedly you will survive. The he'll use his big wind attack so to block it go to the most eastern corner and use reflect to evade it.
Then he'll either do his crazy attack again or start teleporting around. If he teleports then use reflect and when he stops he should get hit and then you can use a combo on him. He may also use stab or slash so use the same strategy in the first part only he will slash more so you'll need to guard more. Repeat until defeated.
And that's my guide on how to beat Xaldin without taking any damage. I don't have one to beat Saix however.
