Nope. The only way you can revive tem is by a save sphere. I know, it sucks but that's just the way the game is made. But you can give the aeon abilities that can heal themselves like cure and curaga. The only way to do that is to defeat Belgimine at the moonflow. She's located just outside the south wharf, I think.

Boy this 'l be fun!

Thanks!

No prob. If you need any more help, you know who to ask.

you can revive aeons by entering battles too. Weaker Aeons like Valefor needs less battle to recover than stronger ones like Anima.

As Axela13 mentioned, The item needed to teach your Aeons Abilities (apart from Yojimbo and Magus Sisters) is called the " Summoner's Soul " Recieved From Belgemine after you defeat her for second time at "Moonflow" you may have met her earlier at the Highroad, and recieved an Echo Ring for a win against her otherwise a Seeker's Ring ..

The reason i mention all this is because as said they learn Abilities one of which is "White Magic", as Axela 13 stated "Cure" needed 99 Hi-Potions...Cura 30 X-Potions...Curaga 60 Mega-Potions.

And as darryl said keep an eye on their battle counts, if your way off a save sphere..

Remember, During Battle the likes of Ifrit, Shiva and Ixion can also be healed with their natural element. Ifrit with fire, Shiva with ice and Ixion with lightning.

The item 'Aeon's Soul,' which can also be aquired by defeating Belgemine, will allow you to raise aeons' attributes using spheres: HP Power Sphere ETC....

True but this costs a lot of mana spheres, I think for Yojimbo (if my memory serves me correct) was somthing like 80HP Spheres for a couple of HP points. I find it best to just teach your Aeons Curaga, Haste and Slow (Anima with this combination can be extremly affective).
