Espers are summoned monsters that Fina calls onto the battlefield. A summoned Esper fights alongside the party for a set number of turns performing its own attacks, then unleashes its signature skill and leaves. Nine Espers exist in total, in line with trophy #36 The Sovereigns of the Planet.

How the Esper system works

  • Fina must be in the active four-member party to issue a summon.
  • Only one Esper can be summoned at a time.
  • The summoned Esper performs its own attacks during its turns, not the party's.
  • When the Esper's turn counter expires, it unleashes its finisher and exits the battle.

This makes Fina a slot you cannot drop for most boss fights — losing the summon slot costs you a finisher, a heal, or a stagger paint depending on the matchup.

Esper's Dwelling and Sealed Esper trials

Each Esper has an associated Esper's Dwelling optional dungeon with a hidden entrance, environmental puzzles, mid-dungeon mini-bosses and the Esper itself as the boss fight. The Sealed Esper trials behave the same way but require prerequisite side content or the area's other objectives before the seal drops. The Antlion counts as a desert Esper trial and unlocks Fina's first summon spell.

Plan the four-member lineup around Fina, a Defender-role tank (Warrior of Light or Charlotte), a healer (Y'shtola or Rhea), and one elemental attacker that matches the Esper's weakness.
