Eidolons are supernatural beings that were once summonable in battle to aid the player. However, they have lost their purpose and are now mere relics for collection.

A list of all Eidolons owned by the player can be viewed from [Options] > [Eidolons].

An eidolon's level is set to the owner's team level. Team level is computed as the average of 3 highest levels in the team or if the team contains only 2 characters, the average level of those two. The ATK and MATK is then set based on this level, using these formulas:

f = (level - 1)/(99 - 1)
ATK = floor([ATK at level 1] + ([ATK at level 99] - [ATK at level 1]) × f1.3)
MATK = floor([MATK at level 1] + ([MATK at level 99] - [MATK at level 1]) × f1.3)

where the known ATK/MATK are listed in the table below.

  • Eidolons were introduced along with Co-op Mode in version 2.0.0.
  • The Eidolons fought in Eidolon quests are the only creatures with the "Eidolon" species.
  • Version 5.5.0 removed Co-op and VS Mode, making Eidolons unsummonable and turning them into collectibles.
    • Eidolons were only summoned in Co-op Mode and VS Mode through the use of a summoning point. Tapping the screen during other players' turns will charge the summoning gauge, which will spawn a summoning point when full. The strength of the Eidolon is determined by the overall level of the player's team.
    • Eidolons were strengthened through the [Strengthen Eidolons] menu in the Tavern. Most Eidolons could be strengthened by using items found in Eidolon co-op quests.
