Six essential resources
Each page has one job. Start with the closest match.
Pink Door location and MysteryKey
The verified 10 Pink Coins → MysteryKey → Top of Castle Pink Door route, including the final cutoff.
You cannot buy the key, cannot find the door, or want the secret boss without route confusion.
Open resourceTwisted Sword Eligibility Checker
Check route state, ThornRing, Shadow Crystal, and save-file readiness before you overwrite progress.
You need a quick yes/no assessment for the save you are currently playing.
Open resourceChapter 5 Weird Route explained
Separate completed Side B, a lake-sequence abort, and the Chapter 2 ThornRing preservation file.
You are deciding which route state to continue or which save file to preserve.
Open resourceChapter 5 secret boss key guide
A no-spoiler checklist for Pink Coins, MysteryKey, Pink Door access, and the reward sequence.
You want the full unlock chain while keeping boss details hidden.
Open resourceChapter 5 walkthrough hub
The full starting point for route decisions, optional content, items, bosses, and post-launch updates.
You need broad chapter help rather than one location, item, or route answer.
Open resourceBoss cheat sheet
Filter fights and compare SPARE conditions, weaknesses, attack notes, and recommended items.
You are already in a fight and need a compact answer instead of a long walkthrough.
Open resourceBefore you overwrite a save
- Treat completed Side B, a Chapter 5 lake abort, and a Chapter 2 ThornRing-preservation file as different states.
- Finish Pink before Flowery’s final-warning cutoff if you want the Chapter 5 Shadow Crystal.
- ThornRing + PureCrystal is the confirmed recipe, but PureCrystal is still unobtainable.
