Guardians are buzzing about the Kell's Fall mission in Destiny 2's latest Act 3 update! 🎮 That mysterious organ in the Bailey isn't just for show – it's the key to unlocking Slayer's Fang shotgun upgrades. But here's the kicker: you gotta serenade it with the right Eliksni notes to reveal secret doors! 💥 Problem is, the darn thing starts with only half its keys active. Talk about a tease! 😤

🔄 Mission Run Strategy
Listen up, space cowboys – you'll need three runs minimum:
1️⃣ First Run: Grab catalyst quests from Eido
2️⃣ Second Run: Collect remaining catalysts
3️⃣ Third Run: CRITICAL – Do this on Expert difficulty!
Pro Tip: "Third run on Expert lets you fully upgrade Slayer's Fang AND unlock all organ codes simultaneously" – saves you grinding!
🎹 Cracking the Organ Puzzle
That funky instrument works like Act 2's "Captive Memory" puzzle but with 13 Eliksni notes (numbered left→right). No sheet music? No sweat! Codes are scattered through the mission:

| Code Effect | Location Hint |
|---|---|
| Opens Frame II | Near starting area |
| Unlocks Frame III | Mirror Gallery dimension |
| Reveals Frame IV | Sanctum encounter zone |
Each code blasts open new doors in Fikrul's Fortress. Input all eight during your Expert run – trust us, it's way smoother than piecing them out!
🔥 Snagging Intrinsic Upgrades
Behind those sparkly new doors? Glowing collectibles holding shotgun upgrades!

A beastly new shotgun (Slayer's Fang!)
-
All intrinsic frames activated
-
Serious bragging rights

That final showdown when you blast through enemies with your fully-upgraded toy? Chef's kiss! 👌 Worth every second of organ-tickling. Now go show the Darkness who's boss! 💪
