Deltarune Chapter 5 Save Editor

Chapter 5 save file facts

Chapter 5 uses the same plain-text V2 layout as Chapters 2, 3, and 4: 3,055 lines with one value per line. The editor reads Chapter 5 from the filech5_* filename and switches to the Festival Day name tables automatically. If a file has been renamed, use the Chapter 5 button in the editor toolbar.

• filech5_0, filech5_1, filech5_2 — the three active Chapter 5 save slots.
• filech5_3 to filech5_5 — Completion FILEs written after finishing the chapter.
• Keep the exact filename — the suffix determines which slot the game loads.

On Windows the folder is %LOCALAPPDATA%\DELTARUNE; on macOS it is ~/Library/Application Support/com.tobyfox.deltarune/. The save file location guide covers Linux and Steam Deck too.

Quit the game before replacing a file, keep the original backup, and watch for Steam Cloud restoring an older copy. Chapter 5 is still receiving game updates, so a backup is non-negotiable.

Festival Day save editing notes

Where Chapter 4's Dark World is one building chain, Festival Day spreads across three outdoor zones, and the editor's Chapter 5 room list follows that map. The Garden covers the Entrance, the Aqua stretch, and the Pink Encounter; the Cliffs pick up at the Garden transition and run through the Dash Runner stretch to the Seth Miniboss; the Flower Castle opens at the Entrance and Foyer, then climbs through the Blue Room, the Fox Hunt, and the Flower Climb before the Pink Room and the Fountain at the chapter's end. Hometown and Castle Town are in the list too, for saves that start or end on the lightner side.

The Chapter 5 tables are not a fresh start — they extend Chapter 4's. Every Chapter 4 entry keeps its exact ID in Chapter 5, which is why a weapon or armor you earned in Chapter 4 still has the same name and meaning in a Festival Day save. The new Festival Day content was given fresh IDs that cannot collide with the old ones: weapons run 30–37, armor runs 30–38, key items run 20–33, consumables occupy 40–43 and 64–70, and the two new spells are ReviveSong and Scythemare. If you are comparing IDs across chapters, that extension pattern is the single most useful thing to know.

Three ID pairs in the new weapon table are easy to mix up. FloweryScarf (34) is the intact version and BrokenScarf (35) its worn counterpart — the editor lets you hold both, which the game normally makes you choose between. WoodBlade2 (30) is the Dark World twin of the light-world Pencil2, and they share a slot pair the way the original Wood Blade and Pencil did. And the consumable table now contains both S.POISON (ID 32, a Chapter 2 joke item) and the new S. POTION (ID 66) — same joke, new chapter, different line in the file.

The light-world inventory table grew as well: Honey Toast, Bread, Seeds, Pencil2, and Petal join the classic light items in Chapter 5. These are separate from your darkner pockets, so stocking up on Festival Day snacks will not crowd out your battle inventory — the two lists are edited independently in the tool.

Because Chapter 5 is still receiving game updates, you may occasionally load a save where an item shows as "Unknown (ID n)". That is the editor being honest, not broken: the game's tables moved before the community's name tables did. The unknown value is preserved exactly through edit and save — do not zero it out to make the label go away, or you will delete an item the game understands fine. Report the unknown ID via hello@deltaruneeditor.com and it can be added to the table in the next update.

The honest state of Chapter 5 flags

Chapter 5 item, weapon, armor, spell, and selected room names are mapped. Dedicated story-flag labels and plot-point recipes are not complete enough to present as safe one-click choices.

The Advanced tab therefore exposes raw flag numbers without guessing. Change those only when you know the exact line and value, and compare against a backup before continuing the game.
