SUMMONING EIDOLONS
Eiko can learn to summon powerful Eidolons by equipping gemstones and other Add-ons until she gains enough AP to summon the being on her own. Her summons involve powerful elemental and non-elemental attacks, and also protective and restorative magic that affects the whole party at once.
There is only a chance that the Eidolon will actually appear during the summons. They always appear the first time you summon them, and thereafter the chance of them appearing during the summons is random. When the Eidolon appears during the summon animation, then the effect is nearly twice as powerful. When Eiko goes into Trance, there is a much stronger chance that the Eidolon will appear. Eiko can make the Eidolon appear each time by learning the Boost ability.
SUMMONING SECRETS
While Eiko only learns to summon four Eidolons throughout the course of the game, you can make some of these beings perform various spells and attacks depending on what Add-on Eiko equips. When you add all of the alternate summons into the equation, as listed in the table that follows, then you can see that Eiko actually has just as many summon variations as Dagger.
In addition, once Eiko learns how to summon Phoenix from a Phoenix Pinion, there is a chance that Phoenix will completely restore the party if everyone gets KO'd. You can determine the percentage chance of this occurring by dividing the total number of Phoenix Pinions in stock by 256. So don't use or sell those Phoenix Pinions; they're hard to come by!
