Final Fantasy Wiki

The Lunar Eidolons (ルナ幻獣, Runa Genjū?, lit. Lunar Phantom Beast) are a group of powerful bosses in Final Fantasy IV. They appear in the GBA and PSP releases in the Lunar Ruins, and each one is fought at the end of a Lunar Trial.


Final Fantasy IV[]

The Lunar Eidolons are stronger versions of Rydia's Eidolons, with the exception of Sylph, Mindflayer, Goblin, Chocobo, Cockatrice and Bomb. 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 summoned into battle it does 9,999 non-elemental damage to all enemies while ignoring their defenses. Some Lunar Eidolons have unique effects in the battle against Zeromus EG. Using a Grimoire opens up the Lunar Trial the player won upon defeating the Lunar Eidolon to be completed again.

Final Fantasy IV: The After Years[]

In the iOS, Android and Steam versions, four of the Lunar Eidolons appear as bosses in the Depths of the True Moon.
