Eiko Carol

When Eiko meets Zidane and the crew, she shows them how truly powerful she is with her summoning power.  Eiko comes along with them because Dagger's interested in learning about summoning, and Eiko has plans on making Zidane hers. >.>

Until Eiko gains enough AP to summon eidolons on their own, she usses gemstones and other add-ons. Her summons involve powerful elemental and non-elemental attacks, and also protective and restorative magic that affects the whole party at once.

Eidolons will not always appear during summons. They always appear the first time, and afterwords they pop up randomly. When the Eidolon appears during the summon animation, the effect is nearly doubled! When Eiko trances, there's a big chance the eidolon will appear.

While Eiko only learns to summon four Eidolons the entire game, you can make some of these beings perform various spells and attacks depending on what Add-on Eiko equips. As you play through the game, you'll see that Eiko actually has just as many summons as Dagger.

Also, when Eiko learns to summon Phoenix, there's a chance he can fully restore all the KO'd people... You can determine the percentage of this occuring by dividing the total number of Phoenix Pinions in stock by 256. So don't use or sell them (although they're expensive) because they're hard to get!
