The Dragon Slayer is one of the most powerful and hardest—to—obtain weapons in Roblox’s Broken Blade. As a 4-star Buster-type weapon inspired by the iconic blade from the Berserk anime/manga, it offers the highest sustained damage per second of any weapon in the game, making it the go-to pick for AFK farming, Boss Rush, and long endgame fights. Getting it takes serious grinding, but this guide walks through every step: where to find it, what materials you need, how to farm the rarest ones, and how to upgrade it once crafted.
| Detail | Info |
|---|---|
| Weapon Type | Buster (4-Star) |
| Location | Eclipse Island (Event Island) |
| Rarest Material | Sacrifice Piece (100 required) |
| Boss to Farm | Black Swordsman (requires Crimson Beherit) |
| Best Boss to Farm Beherits | Velik (AFK-friendly) |
| Post-Craft Upgrades | Forge Master (Muspelheim) / Soul Forge (Jotunheim) |
| Best For | AFK farming, Boss Rush, sustained DPS |
You can find the Dragon Slayer Broken Blade on Eclipse Island, located immediately after Nidavellir Island. It sits directly in front of the Boss Arena on that island. Interact with it to pick up the broken version — this is the starting point for crafting the full weapon.
Note: Some players confuse the name — Eclipse Island has also been referred to as the Event Island or Explosion Island in certain updates. If you’re selecting it from the Teleport Portal menu, look for Eclipse Island or the Event Island option.
Once you have the broken blade version, gather the following to craft the Dragon Slayer:
| Material | Amount Required |
|---|---|
| Money | 3,000,000,000 |
| Gems | 30,000,000 |
| Buster Piece I | 1,000 |
| Buster Piece II | 500 |
| Buster Piece III | 250 |
| Fire Seed | 15,000 |
| Sacrifice Piece | 100 |
Most materials — Money, Gems, Buster Pieces, Fire Seed — accumulate naturally through normal gameplay if you’ve progressed to Eclipse Island. The Sacrifice Piece is the real bottleneck.

The Sacrifice Piece only drops from the Black Swordsman, a spawnable boss on Eclipse Island. To summon him, you need a Crimson Beherit item.
Step-by-step farming process:
Pro Tip: Boost your Luck stat by equipping Titles that give Luck bonuses. Many collection-based Titles reward extra Luck for collecting Gems and other items — these directly increase your Sacrifice Piece and Crimson Beherit drop rates.
Dragon Slayer is a Buster-type weapon. Races that give you a +75% DMG boost — specifically Aesier, Elf, Nether, or Vanir — pair best with it. Among Legendary races, Nether and Vanir are particularly strong due to their weapon-type synergies with Buster builds.
Race rerolls unlock at Level 500+. If you haven’t reached this yet, focus on farming materials first.
After crafting Dragon Slayer, don’t stop there. Enhance it using:
Using higher-rarity Element Materials at either upgrade station provides stronger stat boosts and additional perks. Fully upgrading Dragon Slayer reportedly requires around 3,360 total materials across creation and enhancement costs.
Yes — if you want the best sustained DPS weapon in the game. Dragon Slayer offers the highest overall damage-per-second over long fights, making it better than Moon Cut for AFK farming and Boss Rush. Its Z skill has no cooldown, which is a major combat advantage. Moon Cut edges it out for burst damage on bosses where you want fast kills, so ideally, own both and swap based on content.
It’s found on Eclipse Island (also called Event Island), in front of the Boss Arena. Interact with it to collect the Broken Blade version needed for crafting.
Sacrifice Pieces only drop from the Black Swordsman boss, summoned using a Crimson Beherit on Eclipse Island. Farm Velik for Beherits, then run Easy mode Black Swordsman fights until you have 100 Sacrifice Pieces.

Dragon Slayer wins for sustained damage and AFK farming. Moon Cut deals more burst damage per skill use, making it superior for quick boss kills. Both are endgame-tier — owning both is the ideal setup.
Visit the Forge Master NPC on Muspelheim Island or the Soul Forge on Jotunheim Island and use high-rarity Element Materials to enhance it further.
