Ys Memoire: The Oath in Felghana PS4 and PS5 platinum guide

Ys Memoire: The Oath in Felghana

PS4 / PS5

The museum gallery dictates the route to the Ys Memoire platinum. An Inferno clear does not replace the illustrations tied to lower difficulties. Keep clear data from each run so you can carry over available bonuses and speed up later campaigns. Use the first run to explore and check Redmont events that change as the story progresses.

Ys Memoire remaster on PS4 and PS5. Covers the campaign, Time Attack and museum.

  • Difficulty: Difficulty clears for the gallery and Boss Rush through Inferno.
  • Missables: Check Redmont side quests and save before choices that close a route.
  • Online: Single-player campaign and Time Attack.

Use the first run for Redmont side quests

Return to Redmont after dungeons instead of rushing to the next objective. After the Abandoned Mine, speak to Randolph at the inn, follow the ring quest and save before handing over the Jade Ring. Who receives it changes the outcome. Keep a reloadable save for incompatible choices or note the one to do on a later run.

  • Keep a save from before handing over the Jade Ring.

Upgrade every piece, including early equipment

Gather Raval Ore as you explore and visit the forge after finding new gear. Ultimate Equipment covers swords, shields and armor, including early pieces. On later runs, select the Clear Data bonuses that preserve resources and enable further upgrades. Check every item in the inventory before the ending.

  • Audit all three equipment categories at the forge.

Track cleared difficulties in the museum

The first clear unlocks Inferno. Keep the Clear Data file after each ending and check the museum illustrations tied to each difficulty. Plan Very Easy, Easy, Normal, Hard and Nightmare if their artwork is still missing. Difficulty trophies and museum art do not necessarily follow the same unlock rule.

  • Check the gallery after each clear.

Finish Boss Rush and the two extra bosses

Run each Boss Rush difficulty from Time Attack. Berhardt becomes available after a Boss Rush clear; Black Pikkard opens after the Inferno campaign clear. If a fight is holding you back, check the museum illustrations: the in-game aid is for Time Attack, while the story endings require their own campaign clears.

  • Beat Berhardt and Black Pikkard in their extra fights.

Finish the gallery and watch the Novella prologue

After Boss Rush, return to the Museum and match missing illustrations against your campaign and extra-boss clears. From that menu, watch the Novella prologue to the end for Felghana Archives – Foreword. Keep the completed files until the platinum is confirmed: a difficulty trophy can be unlocked while its illustration is still missing.

  • Check gallery completion and the prologue separately.

Frequently asked questions

Can I play only Inferno?

No. Inferno unlocks after a clear, and Gallery Master also needs artwork tied to other difficulties and Time Attack.

Can I reuse my completed save?

Use Clear Data for the next run to select available carryover bonuses. Keep earlier files as you confirm earned illustrations.

Is watching the story intro enough?

For Felghana Archives – Foreword, open Museum from the main menu and watch the Novella prologue to the end.
