Walkthrough · Chapter 5 of 6 · Self-contained

Mysidia & Cyclone

The ultimate magic, a white mage’s last stand, a city-killing storm, and the Emperor’s first death — none of it is free.

Chapter goals

Chapter 5 checklist

  • Strip Minwu of all gear before the Ultima seal cutscene
  • Clear Tower of Mysidia floors; loot all chests
  • Break the seal; learn Ultima on a character who will actually cast it (Maria is classic)
  • Survive story fallout; prepare for Cyclone
  • Assault the Cyclone fortress-storm
  • Defeat the Emperor (first form)
  • Watch the false victory — hell is not done with him
  • Jade Passage / Pandaemonium (Ch.6)
Dungeon

Tower of Mysidia — full steps

  1. Enter the tower after Cave of Mysidia access is open.
  2. Tall multi-floor dungeon with mages, undead, and heavy traps of attrition.
  3. Rest at safe floors if the PR allows tents; manage MP carefully.
  4. Open every chest — spell tomes and late armor.
  5. At the seal chamber: story forces Minwu’s role.
100% magic

Ultima

  • Minwu expends his life to shatter the seal on Ultima.
  • Strip him before this room if you have not already.
  • After the seal breaks, the party can learn Ultima. Teach it to someone with high Spirit/Intelligence investment — usually Maria.
  • Ultima’s power scales with its spell level: cast it in trash fights later to rank it up before the true final boss.
  • Ultima is a 100% flag for many players even though the story can be beaten without maxing it — rank it if you want the complete toolkit.
⚠ Spoiler — Minwu

Minwu dies permanently here. He is the rebellion’s spiritual center; his death is the cost of ultimate magic.

Set-piece

The Cyclone

  1. The Emperor unleashes a mobile storm fortress: the Cyclone, annihilating towns.
  2. Wyvern / airship story beats get you inside.
  3. Dungeon is vertical and nasty. High-rank weapons matter more than new swords you have not trained.
  4. Heal constantly; enemies hit like endgame already.
  5. Push to the throne of the storm.
Boss

Emperor — first defeat

  • Open with Berserk + Haste on your best physical.
  • White mage full-time Cure; Blink/Protect if available.
  • Ultima / high Black Magic if ranked; otherwise physical ranks carry PR.
  • He falls — celebration is short. Cutscenes send him to hell and bring him back worse.
  • Next: Jade Passage into Pandaemonium (Chapter 6).
After this fight, grind Ultima ranks and HP on overworld/Cyclone leftovers before Jade Passage if the party feels soft.
