Revision 4

Aileen is a Vision in Final Fantasy Resonance and a weaponsmith who is as adept at wielding weapons as she is at forging them. In Square Enix's pre-launch material she is the only Vision with a system attached to her outside of battle.

One of This Game's Own Visions

Aileen belongs to this game's own cast rather than to the legacy roster of heroes drawn from earlier FINAL FANTASY titles. Square Enix has now named nine Visions from that cast: Aileen, Charlotte, Leah, Tronn, Amelia, Camille, Wilhelm, Victoria and Ayaka, with one more not yet named in its official material as of 23 October 2026. The complete roster, legacy heroes included, is at List of Visions.

In Battle

Aileen is an expert at lowering enemy defenses, thanks to her Pilebunker, which pierces its target. Reduced defense pairs naturally with the stagger system, since a party that can push damage through faster reaches a break sooner.

Weapon Forging

Beyond aiding the party in battle, Aileen forges powerful weapons for them, but she requires adamantite to do so.

That makes adamantite one of the game's confirmed reasons to engage with side content and optional dungeons rather than run the critical path.
