Lunar Eidolons

The Lunar Eidolons are a group of powerful bosses in Final Fantasy IV. They only appear in the Advance release in the Lunar Ruins, and one each is fought at the end of a Lunar Trial. The Lunar Eidolons are stronger versions of Rydia's normal summons, with the exception of Sylph, and have HP rising into the six digit range. When defeated each Lunar Eidolon drops a Grimoire that allows the player to summon them into battle by using the Grimoire as an item. When a Lunar Eidolon is called into battle it does 9,999 non-elemental damage to all enemies, ignoring all defenses. Using a Grimoire opens up the Lunar Trial the player won upon defeating the Lunar Eidolon to be completed again.
