Mortal Shell II Black Needle: Location and Guide
[QUICK ANSWER]
The documented Black Needle route runs through Sester’s Gate: a merchant can sell the map, while the Twin Sesters and Stray Sesters fight in Sester’s Bastion are named in the drop description. Its listed ability is Needle Storm.
The direct answer
The Black Needle is a long, sharp spear-like weapon with the listed weapon ability Needle Storm. The location guide says a Black Needle map can be purchased from merchants, then describes the weapon as a drop from the Twin Sesters and the Stray Sesters boss fight inside Sester’s Bastion. Sester’s Bastion is tied to the Sester’s Gate Beacon, and cleansing that Beacon is described as mandatory for reaching the Conquered Temple through Sester’s Gate.
That gives the question a concrete route: look for the merchant map, follow the Sester’s Gate Beacon progression, and reach Sester’s Bastion for the named encounter. A complete room-by-room path or guaranteed drop condition is not documented beyond the guide’s wording. Do not add a different boss, region, or merchant name without an explicit confirmation.
What the weapon is
The Fextralife entry classifies Black Needle as a weapon and describes it as a long sharp weapon with a baton-like structure. Its flavor text says it was stolen from the Twiceborn and lets the bearer reach farther and move more quickly than seems physically plausible. These details establish the weapon’s identity and theme, not a complete moveset or a universal damage ranking.
The separate YouTube guide describes the Black Needle as a spear that can attack from range, has a strong running moveset, and works with many builds. That is a creator’s guide description rather than an official stat table, so use it as combat context only. The safe conclusion is that reach and mobility are the weapon’s documented selling points.
Follow the Sester’s Gate route
The location entry says the map can be purchased from various merchants. It then places the relevant boss fight in Sester’s Bastion, a dungeon inside the Sester’s Gate Beacon. The same guide says that Beacon must be cleansed to pass through Sester’s Gate and reach Conquered Temple.
This sequence is more useful than an invented coordinate because it connects the weapon to a progression landmark. If you have not reached Sester’s Gate, the source does not give a separate early shortcut. If you already have access to the Beacon, use the merchant map clue and the Bastion name to focus your search instead of checking every weapon location in the world.
Needle Storm
Needle Storm is the only weapon ability explicitly listed for Black Needle on the cited page. Its Resolve cost, animation, damage type, area, and upgrade interaction are not documented. This page therefore does not promise a projectile count, stagger value, or best use case.
The general weapons guide says Mortal Shell II’s weapons have unique abilities and extensive upgrade or infusion options. That places Needle Storm within the weapon’s upgrade identity, but it does not fill in Black Needle-specific mechanics. Use the linked video if you need a visual demonstration, and treat the written details as the limit of the guide.
Upgrade snapshot
The Black Needle table lists ten upgrade levels. Its effect column rises from 105% damage at Level 1 to 150% at Level 10, while the material column uses Ventrium for the early levels, Laterite for the final levels, and Coins at every listed stage. These values may change after patches, so treat them as a versioned reference rather than timeless balance data.
| Level | Listed effect | Listed materials | | --- | --- | --- | | 1 | 105% damage | Ventrium x2, Coin x100 | | 2 | 110% damage | Ventrium x2, Coin x100 | | 3 | 115% damage | Ventrium x4, Coin x300 | | 4 | 120% damage | Ventrium x9, Coin x500 | | 5 | 125% damage | Ventrium x13, Coin x1000 | | 6 | 130% damage | Ventrium x18, Coin x1250 | | 7 | 135% damage | Laterite x2, Coin x2750 | | 8 | 140% damage | Laterite x4, Coin x2750 | | 9 | 145% damage | Laterite x9, Coin x3500 | | 10 | 150% damage | Laterite x13, Coin x4250 |
Tarstone notes
The source lists Nightgrasp Stone as Black Needle’s unique infusion Tarstone. It also names Thief’s Stone and Zealot’s Stone as recommended combat Tarstones, and Conqueror’s Reward as a recommended ability Tarstone. These are the source page’s recommendations, not a claim that they are mandatory or universally optimal.
The Steam Deck review explains that Tarstones can add abilities, infuse weapons with debuffs, or provide passive buffs, and that players can equip ten Tarstones at a time. That broader context explains why Black Needle’s Tarstone pairing matters. A full build or verified interaction between Needle Storm and each listed stone is not documented.
What is still unconfirmed
The exact merchant, map price, Black Needle base damage, complete moveset, and drop percentage are not documented here. It is also unclear whether “Twin Sesters” and “Stray Sesters” describe one encounter name or two related encounters. Those details are left out rather than inferred from the weapon’s flavor text.
