Dragon Slayer Guide

The full route to Dragon Slayer — Eclipse Island, Sacrifice Pieces, and the strongest Buster build

Every material, every farm route, every synergy. No RNG guessing.

Recommended Route

Dragon Slayer is the most documented endgame weapon in Broken Blade — a 4-Star Buster weapon found on Eclipse Island. It is the practical daily driver for endgame content: strong enough to farm Jotunheim, survive Sky Spire, and challenge every boss in the game. But getting it requires a serious investment: 3 billion Money, 30 million Gems, 1,750 Buster Pieces, 15,000 Fire Seeds, and 100 Sacrifice Pieces from Eclipse Island bosses. This guide covers the complete Dragon Slayer route: pre-requisite weapons, material farming, best race/element/blessing synergies, infusion recommendations, upgrade path through Forge Master and Soul Forge, and a straight comparison with Excalibur so you know exactly where to spend your grind time.

Quick Answer — How to Get Dragon Slayer

Prepare Soul Devourer (3-Star Buster on Niflheim) as your stepping-stone weapon. You need a reliable Buster for farming Eclipse Island materials.
Complete the Crimson Beherit route on Eclipse Island to unlock access to the Dragon Slayer area. This is the prerequisite quest chain.
Farm the Guts boss on Eclipse Island for Sacrifice Pieces. You need 100 total. This is the longest part of the grind, so settle in.
Collect the remaining materials: Money, Gems, Buster Pieces I-III, and Fire Seeds. These accumulate through normal gameplay but check the tables below to plan your farm.
Head to the Eclipse Island portal area where Dragon Slayer is located. Interact with the crafting station with all materials to forge the weapon.

Complete Material Requirements

Dragon Slayer requires seven different materials. Some build up naturally through normal play (Money, Gems, Fire Seeds), while others need dedicated farming (Sacrifice Pieces, Buster Pieces). Here is the full list:

Material: Money

Amount Required: 3,000,000,000

Primary Source: Natural gameplay

Material: Gems

Amount Required: 30,000,000

Primary Source: Natural gameplay

Material: Buster Piece I

Amount Required: 1,000

Primary Source: Nivaron / Gelaros / Guts (Eclipse) bosses

Material: Buster Piece II

Amount Required: 500

Primary Source: Nivaron / Gelaros / Guts (Eclipse) bosses

Material: Buster Piece III

Amount Required: 250

Primary Source: Nivaron / Gelaros / Guts (Eclipse) bosses

Material: Fire Seeds

Amount Required: 15,000

Primary Source: Exploring islands

Material: Sacrifice Pieces

Amount Required: 100

Primary Source: Guts boss on Eclipse Island

Money, Gems, and Fire Seeds will build up over time as you progress through the game. Make sure you have a stockpile before you start hunting Sacrifice Pieces — the last thing you want is 90 Sacrifice Pieces in your inventory and nothing else to craft.

Step 1 — Prepare Soul Devourer (Prerequisite)

Soul Devourer is the de facto stepping-stone for the Dragon Slayer route. It is a 3-Star Buster weapon found on Niflheim Island that requires Buster Pieces, Fire Seeds, Money, and Gems.
Soul Devourer costs 23 million Money, 24,600 Gems, 300 of each Buster Piece type (I, II, III), and 800 Fire Seeds. It is expensive for a 3-Star weapon, but necessary if you plan to follow the Buster path.
Start collecting Buster Pieces early. They drop from the Nivaron, Gelaros, Niflor, and other late-game bosses. Do not skip boss farming even if you are not ready for the full Dragon Slayer grind yet.
Once you have Soul Devourer, max its level and Soul Forge upgrades before moving to Eclipse Island. A weak Soul Devourer cannot farm Guts efficiently, which extends the entire Dragon Slayer timeline.

Step 2 — Complete the Crimson Beherit Route

Crimson Beherit is the prerequisite material for accessing the Dragon Slayer area on Eclipse Island. You must complete this quest chain before you can reach the Dragon Slayer crafting station.
Farm the Eclipse Island bosses and mobs for Crimson Beherit drops. This is a boss-dropped material, so expect to spend time on boss runs before you even see the first one.
See the full Crimson Beherit guide for exact drop rates, boss mechanics, and the most efficient farming route.
Do not try to skip this step. The Dragon Slayer crafting station is locked behind the Crimson Beherit quest chain, and no amount of materials will let you bypass it.

Step 3 — Farm Sacrifice Pieces from Guts (Eclipse Island)

Guts is the Eclipse Island boss and the primary source of Sacrifice Pieces. This is the real bottleneck for Dragon Slayer — you need 100 Sacrifice Pieces, and each drop requires multiple boss kills.
The Guts boss also drops Buster Pieces (I, II, and III), Fire Seeds, and other materials. So every Guts run progresses multiple requirements at once.
Bring your best Soul Devourer build. Guts on Eclipse Island is significantly harder than earlier bosses, and you need consistent clear times to make the Sacrifice Piece farm tolerable.
Recommended setup: Nether race + Thunder element + Odin or Surtr blessing. This gives the best burst damage for quick boss clears.
One common mistake: expecting Sacrifice Pieces to drop as fast as regular Buster Pieces. The drop rate is lower, and streaks of bad RNG are normal. Budget your farming sessions in hours, not runs.

Step 4 — Collect Buster Pieces, Money, and Gems

While farming Sacrifice Pieces, you will also accumulate Buster Pieces, Money, Fire Seeds, and Gems. But depending on your luck, you may finish Sacrifice Pieces before the other requirements — plan accordingly.
Buster Pieces drop from Nivaron, Gelaros, Niflor, Surtrik, Hraegon, Thorvak, and Guts (Eclipse). Your Buster Piece farming overlaps well with Sacrifice Piece farming since Guts drops both.
Money and Gem requirements are steep (3 billion Money / 30 million Gems). These should come naturally through endgame farming, but if you are short, focus on high-Money islands like Jotunheim or the best Money farming spots in your progression range.
Fire Seeds are used in almost every high-end recipe in Broken Blade. Keep farming them even after you think you have enough — the Excalibur route also needs 15,000 Fire Seeds.

Step 5 — Craft Dragon Slayer at Eclipse Island

Once you have all materials, travel to Eclipse Island and find the portal area where the Dragon Slayer crafting station is located.
Interact with the crafting station and select Dragon Slayer from the recipe list. The craft consumes all materials and gives you the weapon immediately.
If the recipe does not show, verify that you have completed the Crimson Beherit prerequisite quest chain. The recipe stays locked until that quest is done.
After crafting, equip Dragon Slayer and check its level and infusion options. This is the moment your Buster path truly begins — everything before was preparation.

Infusion Recommendations

Dragon Slayer can use different ore combinations during forging. The community has settled on two main paths depending on your budget and goals:
Diamond + Mythril — The cheapest practical base. This combo provides solid damage without gambling rare ores on a weapon that will eventually lead toward Excalibur. Best for players who want Dragon Slayer as a farming tool.
Dunder + Storm — More expensive but stronger. This is the advanced setup for players who plan to main Dragon Slayer as their permanent endgame weapon. The extra damage is noticeable in late Sky Spire floors.
Avoid using Flame or Holy ores on Dragon Slayer if you plan to pursue Excalibur later. Those ores are limited and better saved for the final Excalibur craft.
If you only plan to craft one endgame weapon and it is Dragon Slayer, go with Dunder + Storm for maximum power. If Dragon Slayer is a stepping-stone to Excalibur, stick with Diamond + Mythril.

Best Build — Race, Element, and Blessing Synergy

Dragon Slayer is a Buster-type weapon, and Buster builds reward burst damage and crit-heavy setups. The community has converged on this core synergy:

Slot: Race

Best Pick: Nether or Aesir

Why It Works: Nether provides raw damage bonuses that amplify Buster burst. Aesir is a strong alternative with different stat trade-offs.

Slot: Element

Best Pick: Thunder

Why It Works: Thunder boosts crit chance and crit damage, which directly benefits Buster's heavy-hit style.

Slot: Blessing

Best Pick: Odin or Surtr

Why It Works: Odin and Surtr both add Buster-type damage. Thor, Hel, and Fenrir are viable alternatives for different playstyles.

This setup gives the highest documented burst damage for boss farming. If you are building specifically for Eclipse Island and Guts farming, prioritize Nether + Thunder + Odin above all other combinations.
For players who have already invested in a different race or element: do not reroll for Dragon Slayer alone. The weapon is strong enough to perform well with most setups at endgame level. Reroll only if you are chasing the absolute min-max.

Upgrade Path After Crafting

Crafting Dragon Slayer is only the first step. To unlock its full potential, you need to use both upgrade systems:
Forge Master NPC — Found on Muspelheim Island inside a small volcano behind the Ragaros boss. The Forge Master upgrades the Element Materials applied during forging. Each upgrade level requires more elemental materials and directly increases your weapon's damage output.
Soul Forge — Located on the second level of the central tower on Jotunheim Island. The Soul Forge uses Soul Stones obtained from Jotunheim mobs and Sky Spire. This is a separate upgrade path that stacks with Forge Master upgrades.
Priority order: first max the Forge Master upgrades for your infused elements, then push Soul Forge levels. Soul Forge upgrades take longer but have a bigger impact on endgame performance.
Buster Pieces are also used for Soul Forge upgrades. Make sure you collect extra Buster Pieces beyond the crafting requirement if you plan to push Soul Forge levels.
Once Dragon Slayer is fully upgraded, it becomes your primary tool for farming Holy Grails (for Excalibur), Sky Spire floors, and any endgame content. See the Excalibur guide for the full late-game rotation.

Dragon Slayer vs Excalibur — Which Should You Get?

This is the most common question in endgame Broken Blade. The short answer: Dragon Slayer first, Excalibur second.
Dragon Slayer is the practical daily driver. It costs fewer rare materials (no Holy Grail farming required), performs at a high level for all endgame content, and is strong enough to farm everything you need for Excalibur. If you only craft one endgame weapon, make it Dragon Slayer.
Excalibur pulls ahead in raw damage and AoE coverage. In speed runs, high-level boss fights, and endgame content where every second counts, Excalibur outperforms Dragon Slayer. But the Holy Grail grind (100 Holy Grails from Sky Spire Floor 41+) is a multi-day commitment.
Think of it this way: Dragon Slayer gets you to the endgame. Excalibur dominates once you are there. The best progression path is Dragon Slayer → Soul Forge upgrades → Excalibur.
See the Excalibur guide for the full comparison with material costs, farm routes, and infusion recommendations.

Progression Tips

Start collecting Buster Pieces the moment you unlock late-game boss content. Do not wait until you decide to craft Dragon Slayer — the piece farming takes longer than you expect.
Prioritize Soul Forge levels early. Even before you craft Dragon Slayer, Soul Forge upgrades on Soul Devourer improve your farming efficiency for the Dragon Slayer materials.
Do not split resources between weapon types. If you have chosen the Buster path, commit to it. Selling or abandoning a Buster weapon to start Sword or Katana from scratch wastes your entire material investment.
Save Fire Seeds aggressively. Both Dragon Slayer and Excalibur need 15,000 each. If you plan to pursue both, that is 30,000 Fire Seeds total — one of the highest material requirements in the game.
Use the Crimson Beherit guide to speed up the Eclipse Island prerequisite. Many players waste time exploring Eclipse Island before knowing the exact boss farming route.
Track your Sacrifice Piece count. 100 pieces is a long grind, and losing count or stopping early delays the final craft. Use a notebook or in-game counter.
