Black Briar is a Mythical-rarity dagger in Grand Blue built around speed and self-healing rather than raw damage. Its basic attack lands five quick strikes that interrupt enemy abilities and restore health through a 25% lifesteal, which makes it one of the most reliable weapons for long boss fights. You do not find it as a random drop. You build it at a crafting station once you have the right materials.
Quick answer: Craft Black Briar at the Forge crafting table using 2 Obsidian and 1 Handle. Obsidian drops from World Boss Chests, and the Handle is crafted from 1 Cloth and 2 Sticks.
Materials required to craft Black Briar
The final craft needs just two ingredients, but one of them has to be built first and the other is rare. Here is what each piece costs and where it comes from.
| Material | Amount | Source |
|---|---|---|
| Obsidian | 2 | World Boss Chest (rare drop) |
| Handle | 1 | Crafted from 1 Cloth + 2 Sticks |
| Cloth | 1 | Dropped by enemies and breakable containers |
| Sticks | 2 | Breaking wooden boxes, barrels, and crates |
Build the Handle first
The Handle is not sold anywhere, so you make it yourself before the Black Briar recipe becomes available. Gather the two base materials, then combine them at the crafting station.
Farm Obsidian from world bosses
Obsidian is the gate on this weapon. It has no shop or crafting method and only appears inside World Boss Chests, which is why it is one of the rarest chest rewards in the game. You will likely need to run several bosses before you have the two you need.
World bosses are the strongest enemies in Grand Blue, with huge health pools and heavy damage. They spawn at regular intervals on a server, and an on-screen alert tells you the location when one arrives. Reach the spot, enter the boss portal, and wait for the preparation timer to finish. Up to eight players can join a single fight, so teaming up helps you clear it faster.
Every player in the raid receives a World Boss Chest when the boss dies, along with EXP, Gold, and Celestial Coins. Axe-Hand Logan and Choppy the Clown are two examples of world bosses, each with its own attack patterns.
| Reward | Drop rate |
|---|---|
| Whetstone | 52.9% |
| Celestial Coin Pouch | 15% |
| Smith’s Clamp | 12% |
| 2x Diamond | 10% |
| Embarrassment (Axe-Hand Logan only) | 5% |
| Fruit Chest | 4% |
| Expert Treasure Map | 3% |
| Marine Captain’s Cape | 2% |
| Obsidian | 1% (0.5% from Choppy the Clown) |
| Flame Ring | 0.5% |
| Crew Reforge Sigil | 0.01% |
Keep running world bosses even after you have your two Obsidian, since they are also one of the faster ways to earn Gold.
Craft Black Briar at the Forge
Once you have 2 Obsidian and 1 Handle in your inventory, the final craft takes seconds.
Level requirement and weapon stats
You can craft Black Briar at any point, but you must be at least Level 110 to equip and use it. The dagger has low base damage that is offset by an extremely fast swing, so it lands more hits over time and heals you with each one.
| Stat | Value |
|---|---|
| Rarity | Mythical |
| Level requirement | 110 |
| Base damage | 3 |
| Swing speed | 0.34s |
| Range | 7.5 studs |
| M1 lifesteal | 25% |
Its basic attack chains five hits, one more than most weapons, so every combo triggers lifesteal more often. As a dagger, it currently has access to only two skills, Sword Lunge and Power Slash, both of which have good range and can be used together to clear marines quickly. Level the weapon up by using it against enemies to unlock those skills.
The gathering steps are quick, so the real time investment is farming Obsidian. Once you have both pieces in hand and hit Level 110, Black Briar becomes a strong sustain option that lets you heal through boss damage instead of just absorbing it.
