Finding a Northlander Polearm Billet requires targeted weekly boss farming or regional progression rewards. If you're trying to craft four-star weapons like the Crescent Pike or Dragonspine Spear, you need this specific crafting material. It doesn't drop from standard enemies, and casual exploration won't yield reliable results.
Knowing exactly where to look saves hours of wasted resin and effort. Let's break down the most efficient drop sources, conversion methods, and optimal weapon choices for your characters.
Primary Sources for Northlander Polearm Billets
The most consistent method to obtain a Northlander Polearm Billet is challenging weekly Trounce Domain bosses. These encounters reset every Monday, giving you regular chances at rare prototype drops.
- Stormterror (Dvalin): Located in Stormterror's Lair, this classic Mondstadt boss carries a chance to drop regional weapon prototypes.
- Andrius (Lupus Boreas): The Wolf of the North in Wolvendom offers weekly rewards that include this specific polearm material.
- Childe (Tartaglia): The Golden House domain in Liyue adds another weekly roll for your required crafting item.
- Azhdaha: Beneath the Dragon-Queller tree, this massive boss drops regional prototypes alongside character ascension gems.
- La Signora: Located in Inazuma City, her domain also features the standard prototype drop table.
Keep in mind that boss drops are randomized. You might receive a sword or catalyst prototype instead of a polearm. Patience is part of the grind.
One-Time Exploration Rewards
If you haven't exhausted your early-game exploration, you can secure guaranteed Northlander Polearm Billet drops through specific progression milestones:
- Frostbearing Tree (Level 8): Upgrading this tree in Dragonspine using Crimson Agate rewards you with one guaranteed polearm prototype.
- Sacred Sakura's Favor (Level 24): Offering Electro Sigils to the Grand Narukami Shrine grants a billet.
- Liyue Harbor Souvenir Shop: You can purchase a single prototype using Geo Sigils if stock hasn't been cleared out.
- Spiral Abyss: Clearing specific early chambers, such as Floor 3 Chamber 3, yields one-time weapon prototype rewards.
Converting Billets Using Dream Solvent
If your weekly boss runs yield other regional prototypes like Midlander or Borderland variants, you aren't completely stuck. Crafting benches feature an alchemy conversion tab that solves this RNG wall.
- Combine 1x Northlander Polearm Billet (or another regional equivalent) with 2x Dream Solvent at any crafting bench.
- Dream Solvent drops from the same weekly bosses, making it easy to swap surplus weapon prototypes into the exact material you need.

Best Weapons to Forge
Once you secure your material, you need to decide which four-star weapon to craft. Each option requires specific secondary ores alongside your Northlander Polearm Billet.
- Crescent Pike: Requires 50 Crystal Chunks, 50 White Iron Chunks, and 500,000 Mora. It excels on physical damage dealers like Xiangling due to its powerful passive scaling on normal attacks.
- Dragonspine Spear: Requires 50 Starsilver, 8 Empowered Dragontooth, and 500,000 Mora. This weapon fits budget physical builds acquired through the Festering Fang world quest line.
- Kitain Cross Spear: Requires 50 Amethyst Lumps, 50 White Iron Chunks, and 500,000 Mora. It provides Elemental Mastery and helps energy regeneration for reaction-focused characters.
Common Mistakes to Avoid
Players often waste resources or miss out on efficient progression due to a few common errors:
- Ignoring Weekly Bosses: Skipping discounted weekly boss entries limits your chances at both Dream Solvent and weapon prototypes. Always clear at least three bosses per week.
- Forcing the Wrong Weapon: Don't forge the Crescent Pike if your primary character scales entirely on elemental reactions rather than physical damage. Match the forged weapon's passive to your team composition.
- Forgetting Alchemy Conversion: Many players sit on dozens of unused bow or catalyst prototypes without realizing Dream Solvent can swap them into polearm materials.
Frequently Asked Questions
Can I buy infinite Northlander Polearm Billets?
No. Vendor stocks in Liyue Harbor are strictly one-time purchases. After that, you must rely on weekly boss drops or crafting bench conversions.
Which boss has the highest drop rate for polearm billets?
All weekly Trounce Domain bosses share similar randomized drop tables. No single boss offers a higher statistical drop rate for polearms over other weapon types.
Is the Crescent Pike still worth crafting?
Yes. For physical damage main-DPS characters who rely heavily on normal and charged attack strings, the Crescent Pike remains one of the strongest craftable options available.
What should I do if I only get Midlander billets?
Save your Dream Solvent from weekly boss clears and use the alchemy crafting bench to convert those Midlander items directly into the older regional variant you need.
