Where to Find the Black Needle in Mortal Shell 2 — Complete Walkthrough to the Sester’s Bastion, Bell Puzzle Solution & Boss Fight Guide

Reach further. Strike faster. Kill everything. 2The Black Needle is a Weapon in Mortal Shell 2. The Black Needle is a long sharp weapon with a baton-type structure that would be good for striking Enemies. 2Stolen from the Twiceborn, this spear enables the bearer to reach further and more quickly than seems physically plausible.4 The Black Needle is one of the eight weapons tucked away in the region of Mammon, and it’s an easy recommend for the mid-game thanks to its reach. But finding it requires navigating one of the game’s trickiest dungeon puzzles and beating a multi-phase boss fight that catches unprepared players off guard. 4 Grabbing it isn’t about grinding or shopping — it’s a single, mostly-skippable run out to one beacon, a short puzzle, and one boss fight. This guide covers the exact path, the bell puzzle solution, and the boss strategy that gets this devastating spear into your hands.

Quick Answer — The Fast Version

4 To get the Black Needle in Mortal Shell 2, go to the Sester’s Gate Beacon from the Outskirts of Mammon, enter Sester’s Bastion, solve the bell-platform route, then defeat the Sester boss at the end to receive the spear.

Step	Summary
1	Travel to the Outskirts of Mammon
2	Head east to the Sester’s Gate Beacon
3	Cleanse the beacon to unlock Sester’s Bastion dungeon
4	Take the lift down into the dungeon
5	Solve the bell-platform puzzle (ring bells to create bridges)
6	Defeat the Twin Sesters boss
7	Defeat the Stray Sesters (second phase)
8	Black Needle drops automatically

Now let’s break down every step in detail.

Step 1: Getting to the Sester’s Gate Beacon

4 Everything about this weapon lives in the same corner of the map: you cross the Outskirts of Mammon, cleanse the Sester’s Gate Beacon to open its dungeon, and the spear is handed to you for clearing what’s inside.

The Route from Marrow Keep

Step	Direction	Landmarks
1	Start at Marrow Keep (the hub area)	Your home base
2	Head into the Outskirts of Mammon	Eastern region of the map
3	3Head to the Sester’s Gate beacon on the far east side of the map.	Follow the path east
4	Look for the beacon structure	Distinctive glowing pillar
5	3Once there, cleanse the beacon to unlock its dungeon, Sester’s Bastion, and take the lift down.	Interact with the beacon

Step 2: Entering Sester’s Bastion — The Dungeon

After cleansing the Sester’s Gate Beacon, a dungeon entrance opens up. 5To get the Black Needle, head east to reach the Sester’s Gate Beacon. Enter and make your way to the Sester’s Bastion.

Dungeon Detail	Info
Dungeon Name	Sester’s Bastion
Located Inside	Sester’s Gate Beacon
Entry Method	Cleanse the beacon → take the lift down
Difficulty	Medium-Hard
Key Mechanic	Bell-platform puzzle
Boss	Twin Sesters → Stray Sesters
Reward	Black Needle + Sester’s Crest

2 This Dungeon is located inside the Sester’s Gate Beacon, which is mandatory to cleanse if you want to go through the Sester’s Gate and reach the Conquered Temple. This means clearing Sester’s Bastion for the Black Needle also progresses the main story — it’s not just a weapon side-trip, it’s on your critical path.

---

Step 3: The Bell-Platform Puzzle — How to Cross the Gaps

This is where most players get stuck. 4The dungeon’s only real snag is the bells, which raise stone paths across gaps that otherwise look like dead ends.

First Bell Set (After the Lift)

4 Right after the lift and the first drop, you’ll see two platforms that aren’t connected to yours yet, along with two bells — one just to your left and one higher up on the right. Ring both with your sidearm and a stone walkway bridges the first gap.

Step	Action	Result
1	Drop down from the lift	Land on the first platform
2	Look LEFT — spot the first bell	Visible on a nearby ledge
3	Shoot the bell with your sidearm	Bell rings — first path section raises
4	Look RIGHT and UP — spot the second bell	Higher up on the right side
5	Shoot the second bell with your sidearm	Bell rings — path completes
6	Cross the newly raised stone walkway	Proceed deeper into the dungeon

Second Bell Set (The Bridge Room)

4 The trickier set is in the larger bridge room further in. Clear the enemy camps there first, because it’s a rough spot to fumble a puzzle.

Step	Action	Critical Note
1	Enter the larger bridge room	Multiple platforms visible
2	CLEAR ALL ENEMIES FIRST	⚠️ Do NOT attempt the puzzle while enemies are alive
3	Locate bells around the room	They’re on walls, pillars, and elevated positions
4	Shoot each bell with your sidearm	Stone bridges raise sequentially
5	Cross the completed bridge path	Leads to the boss arena entrance

Pro Tip: Use a ranged sidearm with decent accuracy — you need to hit bells at various distances. 6Better yet, pair it with the Forgotten Crossbow as a sidearm for a quick option for dealing with even longer-range encounters.

Step 4: The Boss Fight — Twin Sesters + Stray Sesters

This is the final challenge standing between you and the Black Needle. 6You’ll have to work through a fairly challenging dungeon within the beacon, which is capped off by a boss fight against multiple Sesters.

Phase 1: Twin Sesters

5 Continue on to the dungeon, defeating any enemies you encounter along the way, until you reach the Twin Sesters. Defeat them to obtain the Black Needle.

Boss Detail	Info
Boss Name	Twin Sesters
Type	Dual boss — two enemies simultaneously
Difficulty	Medium-Hard
Arena	Open room at the end of Sester’s Bastion
Key Challenge	Managing two enemies at once

Twin Sesters Strategy

Tip	Why It Works
Focus one Sester at a time	Splitting damage between both prolongs the fight dangerously
Use Harden timing	Harden absorbs hits from the second Sester while you DPS the first
Keep both in your camera	Never let one go off-screen — they’ll punish blind spots
Dodge toward the passive one	Create distance from the aggressive Sester
Use ranged sidearm between combos	Chip damage adds up when you can’t safely melee
Watch for synchronized attacks	Both may attack simultaneously — Harden or dodge through

Phase 2: Stray Sesters

3 Once both are dead, a second boss, Stray Sesters, will appear. Defeating it drops the Black Needle, along with the Sester’s Crest, which can be traded for 3,000 gold.

Boss Detail	Info
Boss Name	Stray Sesters
Type	Solo boss — appears after Twin Sesters
Difficulty	Hard
Drops	Black Needle (weapon) + Sester’s Crest (3,000 Gold trade item)
Key Challenge	Higher damage + more aggressive than the Twins

Stray Sesters Strategy

Tip	Why It Works
Heal between phases	Use items before Stray Sesters appears — brief window
Learn the attack patterns	More aggressive than the Twins — longer combo strings
Punish recovery animations	After big attacks, the boss has a brief recovery window
Don’t get greedy	2–3 hits maximum per opening — then dodge away
Harden during combo strings	Absorb one hit → counter → retreat
Use the full arena	Kite around the room to create healing windows

6 This can be quite an ask if you’re lower level, so it’s best to tackle this later in the game.

Step 5: Claim Your Reward — The Black Needle Is Yours!

6 Once you’ve defeated the bosses, you’ll automatically be granted the Black Needle.

Reward	Detail
🗡️ Black Needle	Spear weapon — long reach, fast strikes
💰 Sester’s Crest	Tradeable item — worth 3,000 Gold
🏰 Beacon cleansed	Sester’s Gate opened — main story progression
⚗️ Three Ova	3After the fight, cleanse the corruption, collect the three Ova, and return to the beacon.

Don’t Forget the Post-Boss Steps!

3 Cleansing it also clears the entrance to the corrupted gate behind it, which leads to one of the game’s main bosses. This means getting the Black Needle simultaneously unlocks major story content — making this one of the most efficient dungeon runs in the game.
