Broken Blade Weapons Guide
All weapon types, rarity tiers through top-star crafts, and the full weapon list — plus unlock steps for Explosion and Yamato.
By Bloxron Editorial Team · Last updated
Overview
Every weapon in Broken Blade is unlocked and upgraded through crafting — not picked up as random loot. You find locked weapons in the world, spend weapon pieces and boss materials to activate them, then forge element materials onto the finished blade. ★★★★ capstones include Excalibur (Holy Grails from Sky Spire) and Dragon Slayer (Sacrifice Pieces on Explosion Island); ★★★★★ targets are Yamato and Explosion.
Weapon Types
| Type | Combat Style | Strength | Limitation |
|---|---|---|---|
| Sword | Balanced melee | Consistent damage and flexibility | Limited burst potential |
| Katana | Fast combo-focused | High speed and critical scaling | Lower raw survivability |
| Buster | Heavy burst damage | High boss damage output | Slow attack timing |
Rarity Tiers
| Rarity | Stage | What it means |
|---|---|---|
| ★ | Early | Starter weapons for first islands |
| ★★ | Early-mid | First crafted upgrades (e.g. Wind Fang, Stone Cleaver) |
| ★★★ | Mid-game | Needs boss materials and steady farming |
| ★★★★ | Endgame | High material cost — Excalibur, Moon Cut, Dragon Slayer |
| ★★★★★ | Capstone | Explosion (Buster) and Yamato (Katana) — event and update crafts |

How to Upgrade a Weapon
- Discovery — find the locked weapon object in the world
- Unlock — pay currency plus the matching weapon pieces (Sword, Katana, or Buster)
- Craft — spend boss materials to activate the base form
- Forging — spend boss materials to finish the weapon form
- Enhancement — late-game upgrades for extra power
Material names are on the materials guide; drop sources on the bosses guide. Match your weapon to a race (Elf / Vanir / Nether) on the races guide.
Dragon Slayer Requirements
Dragon Slayer is the ★★★★ Buster capstone. Budget for a long farm — not a single boss run. Step-by-step routes are in the Dragon Slayer guide.
| Requirement | Notes |
|---|---|
| Buster Pieces | Large stack across multiple farming sessions |
| Sacrifice Piece | Top-tier boss material — island and event bosses |
| Element materials | Ongoing farm; pick an element that matches your build |
| Currency | High unlock and crafting fees |
Excalibur (★★★★ Sword)
Excalibur is crafted at the Jotunheim tower forge — not dropped from a boss. Budget Sky Keys and tower time before you start the Holy Grail stack. Full floor bands and forge steps are in the Excalibur guide.
| Requirement | Detail |
|---|---|
| Holy Grail | 100 from Sky Spire floors 41+ |
| Craft station | Top of the Jotunheim tower — Excalibur forge station |
| Infusion tip | Two Holy and two Flame infusions are a common pairing for the finished blade |
Soul Forge & Weapon Ascension
Weapon Ascension adds a second power layer after Soul Forge. Breakthrough rolls a multiplier that scales the ascension stat bundle — chase a high roll on your main carry, not on a weapon you will replace.
- Unlock: Soul Forge level 12 on the weapon you plan to keep
- NPC: Jotunheim tower — level 1, next to the Soul Forge NPC
- Breakthrough: Roughly 1.1× through 2.0× — higher multipliers are rarer
- Materials: Arkenstone and Holy Grail
Soul Stones from Jotunheim guardians feed Soul Forge levels. Full farm order and Breakthrough tips are in the Ascension guide; Arkenstone and Holy Grail details on the materials guide; Charon and high-floor routes on the bosses guide.
FAQ
How does weapon progression work in Broken Blade?
Find a locked weapon in the world, spend currency and weapon pieces to unlock it, then craft and forge it with boss and element materials. Late-game enhancement adds more scaling on top.
Which weapon type should I choose?
Sword — steady damage and flexible combos. Katana — fast attacks and crit scaling. Buster — slow swings but high burst for bosses. Pick based on how you want to fight, not raw stat numbers.
Where do Elements fit in?
Elements are passive buffs rolled with Element Rerolls at level 500. They stack on your character, not on the weapon itself. See the Elements and Bosses guides for tier picks and Velik farming.
What does Dragon Slayer need?
Dragon Slayer is a ★★★★ Buster weapon on Explosion Island. Farm Sacrifice Pieces from Guts, stack Buster pieces and element materials, and redeem Truth Scroll and Void from milestone codes when available — full route in the Dragon Slayer guide.
How do I craft Excalibur?
Excalibur needs 100 Holy Grails from Sky Spire floors 41+, crafted at Jotunheim tower level 3. Budget Sky Keys from Jotunheim guardians first — see the Excalibur guide for floor bands and forge prep.
How do I get Explosion and Yamato?
Explosion is a 5-Star Buster weapon — craft on Explosion Island after farming Eye Patches from Headless Knight. Yamato is the 5-Star Katana — craft on Midgard Island with Red Orbs, Katana pieces, and the Space forge element.
How does Weapon Ascension work?
After Soul Forge 12, talk to the Ascension NPC on Jotunheim tower level 1. Spend Arkenstone and Holy Grail on Breakthrough rolls to raise your ascension multiplier — only invest on a weapon you plan to keep.
