Where to get Black Needle
The location details say a Black Needle map can be purchased from merchants, then place the weapon in Sester’s Bastion near the Sester’s Gate Beacon. The encounter is described with the names Twin Sesters and Stray Sesters. Cleansing the Beacon is also described as necessary for reaching Conquered Temple through Sester’s Gate.
This gives you a progression landmark to follow: reach Sester’s Gate, use the merchant-map clue, and search Sester’s Bastion. A room-by-room route and guaranteed drop condition are not listed, so no coordinate or extra boss is added.
Requirements
No level gate, key item, map price, or exact merchant name is documented for Black Needle. The practical requirement that is clear from the route is access to the Sester’s Gate and Sester’s Bastion area.
Weapon ability
Needle Storm is the listed Black Needle ability. Its Resolve cost, animation, damage type, area, and upgrade interaction are not listed, so this guide does not promise a projectile count, stagger value, or universal best use.

Treat these as a versioned reference because balance and upgrade costs can change after patches.
Combat use
The available combat guide describes Black Needle as a spear with reach, ranged attacks, and a strong running move. Use those as practical combat cues rather than as a complete stat ranking.
Nightgrasp Stone is listed as Black Needle’s unique infusion Tarstone. Thief’s Stone, Zealot’s Stone, and Conqueror’s Reward are also listed as recommendations for combat or ability use. These are options, not mandatory combinations. The wider Tarstone system can add abilities, infuse weapons with debuffs, or provide passive buffs.
