Fifth Chorus

A Silksong mod that reworks the Fourth Chorus boss, adding a faster fight flow, extra phases, and some quality-of-life features when fighting it.

Features

• Reworked Fourth Chorus Boss Fight

The Fourth Chorus encounter is reworked to create a more difficult, but fun fight.

Patterns are adjusted to avoid repeats, boss logic is smarter, and the boss has a completely new 4th phase.

• In-Game Boss Config Menu

Press F6 (configurable) to open a custom Boss Config menu:

• Choose a difficulty, see a description, then press Start to jump into the fight
• Difficulty Presets (Free Play / Easy / Medium / Hard)

Each difficulty configures the player’s stats before teleporting:

• Free Play

Use your current save’s gear, tools, masks, and silk. No changes applied.

• Easy

7 masks, 9 silk, no upgrades.

• Medium

6 masks, 9 silk, no upgrades, no non-combat silk skills (except dash and cloak).

• Hard

5 masks, 9 silk, no tools, no upgrades, no non-combat silk skills (except dash and cloak).

• Instant Teleport to Fourth Chorus Arena

Upon starting the fight, the mod warps directly to the Fourth Chorus room:

• Scene: Bone_East_08
• Gate: right1

This can be done at any time once loaded in, as long as the game is not paused.

• Save Blocking (Safe Sandbox Mode)

All calls to GameManager.SaveGame are intercepted and skipped:

• No autosaves or manual saves while the mod’s patch is active
• Your real save file won’t be altered by using this mod

As a result, you do not need a dedicated save file to play with this mod. Any save you have will work.

It is still always recommended to back up your save when playing with mods.
