Side Content

Introduction

Beyond the main story, FINAL FANTASY RESONANCE is packed with optional content for completionists. The wandering swordmaster Gilgamesh awaits players who seek him out across the world, offering a legendary multi-stage encounter. A monster Colosseum hosts deadly battles with rewards to match, while the Chamber of Arms seals formidable foes within legendary weapons — a true gauntlet for prepared parties. The ultimate challenge is a showdown with Ultima Weapon, one of the game's most anticipated optional battles. This hub covers all of it: where to find each piece of side content, what you need to prepare, the rewards on offer, and a full roadmap to 100% completion in the 60-80 hour range.

Side Content Overview

Optional Content Guide

Core Mechanics

Side content in FINAL FANTASY RESONANCE is structured to test every part of your mastery. Gilgamesh's wandering multi-stage encounter punishes players who rush through the story, rewarding those who return to regions at different points. The Colosseum offers repeatable arena battles with scaling difficulty, making it a reliable source of endgame items and gil for players who enjoy the combat loop. The Chamber of Arms is the completionist gauntlet — a series of superbosses sealed in legendary weapons that demand a fully built party. And Ultima Weapon caps the optional content as the ultimate battle, a final check on your Visions, espers, jobs and strategy. Every piece of side content feeds back into power, so the detours are never wasted.

Advantages

The breadth of side content is a genuine strength for a game positioned as a classic Final Fantasy experience. The roster of optional challenges — Gilgamesh, the Colosseum, the Chamber of Arms and Ultima Weapon — gives completionists clear goals across the full 60-80 hour run and mirrors the iconic optional content of the series' golden era. Because the rewards include legendary weapons and rare items, side content feeds directly back into your power, making the detours feel worthwhile rather than filler. For players who love the combat system, the Colosseum also offers a repeatable arena to test and refine builds.

Challenges

As a pre-release title, the details of the side content are still thin. Exact Gilgamesh encounter locations, Colosseum reward tables, the full Chamber of Arms roster and Ultima Weapon's battle mechanics are based on the official feature list and previews rather than real gameplay. The completion estimate of 60-80 hours for 100% completion is a projection and could shift either way. We will refine these pages with confirmed locations, boss patterns and reward data once the game launches on October 22, 2026.
