Is there any way characters like Yuna can learn Auto-Life? Also (I bet everyone has heard this before) I need help on the Chocobo race to get the Sun Sigil. Can anyone please help me?

Everyone should be able to learn Auto-Life, as it's on the Sphere grid afaik. As for the Chocobo race, I can't really give you any good advise other than to keep trying/practicing.

Auto-Life is protected by pesky level four sphere things, somewhere on the grid. I can't tell you where it is, because I haven't played the game in years.

It might be where you start Karmai or whatever his fucking name is...

Like Neo Xzhan said, everyone can learn auto-life. Yuna starts right where the Level 4 lock is that blocks Auto-life. You will definately not be able to get it in the beginning of the game, but must return later on to get it. For the sun sigil, just try to concentrate and not hit the birds and get as many balloons as you can. You get better and better and eventually you will get it. That's all i can give.

Well for Auto-Life i have a return sphere. I'll Use that on Yuna or use a teleport sphere. For the Chocobo racing my best time was 0:2.9. I cannot get past that because those determined birds are dying to hit you.

I always try to get balloons as my priority while doging birds.

Ahh. The last time, i tried to get the sun sigil, which was like 3 weeks ago, i got it on my fourth attempt. Luck plays a huge factor. If at the beggining, the balloons are on the trainers side, i dont think you can get it. But, if you manage to get the first set, right near the beggining, just swerve as far away from the oncoming birds as possible, without straying to far away from the balloons. Like i said, this is quite hard, and impossible without a bit of luck.
