Visions serve as memory-based skill sets in Square Enix's Final Fantasy Resonance, enabling players to customize character abilities across five roles: sentinel, commando, breaker, saboteur, and medic. Each Vision grants unique battle skills and mastery bonuses that persist even when swapped between characters. Acquisition requires progressing through story chapters, completing side quests, or defeating specific bosses, with some locked behind prerequisites like reaching designated areas or unlocking the airship. For example, Cloud's Vision becomes available after obtaining a chocobo in Chapter 1, while Sephiroth's requires unlocking the airship in Chapter 5 and defeating him in a whirlpool battle. Mastery bonuses, earned by accumulating points through battles with Visions equipped, allow permanent skill upgrades but demand separate rank progression per character. The game features 26 total Visions, including cameos from iconic series figures like Noctis and Lightning, alongside original additions such as Aileen and Victoria. Locations range from the Dwarven Forge to Mysidia, with progression often tied to chapter milestones. Though none of the unlocking methods present significant difficulty, players must revisit earlier regions to access missed Visions, making early prioritization advisable for optimal campaign support.
