Black Reaper is one of the most eye-catching melees you can get in Sailor Piece right now. It comes with a full quest line, a detailed boss summoning system, and a damage kit that hits hard across all difficulty levels. This guide shows you all you need to know about Black Reaper melee in Sailor Piece, how to get it, and what to expect from it.
How to Get Black Reaper Melee in Sailor Piece
Before getting the Black Reaper melee fighting style, you first need to complete the Blood Flower quest. This is not optional. Finishing it is what unlocks Isolation Island in Sea 2, which is where the entire Black Reaper grind takes place.

Once you have access to the island, you can start working toward the melee.
Step 1: Farm Reaper Keys
Once you are on Isolation Island, your first job is collecting Reaper Keys. These drop from Ghoul Master NPCs on the wooden bridges and walkways near the arena area.
Since summoning the boss consumes keys depending on the difficulty level, it’s a good idea to keep some spare keys ready so you can continue farming the materials without interruptions.

The number of keys you need depends on how hard you want the fight to be:
| Difficulty | HP | Reaper Keys Needed |
|---|---|---|
| Normal | ~50 Billion | 1 |
| Medium | ~100 Billion | 2 |
| Hard | ~300 Billion | 3 |
| Extreme | ~800 Billion | 4 |
Step 2: Summon the Black Reaper Boss
To summon the Black Reaper boss, you need to go inside the dome located in the center of the building. Interact with the Black Reaper Summoner NPC to trigger the option to spawn the boss. Keep running these boss fights and collecting drops until you have all the required materials.

Step 3: Collect All Required Materials
This is the part that takes the most time. Find the Black Reaper Seller on one of the floors on the building wall. To buy the Black Reaper Melee, you need to gather all of the following:
- One-Eyed King Title
- 65,000 Gems
- 20x Black Shards
- 12x Reaper Remnants
- 5x Rinkaku Cores
- 2x Ghoul Essences

Most of these come from farming the Black Reaper boss repeatedly, so the more efficient your runs are, the faster you will clear this list.
Buy Using Robux
If you would rather not farm, you can unlock Black Reaper instantly through the in-game shop using Robux:
- Black Reaper + Ghoul Outfit — 1,399 Robux
- Black Reaper only — 1,599 Robux
Worth noting that the bundle actually costs less than buying the melee alone, so if you want the outfit too, that is the better deal.
Black Reaper Skills Breakdown

Once you have the Black Reaper melee, here is what the full kit looks like:
| Move | Description | Damage |
|---|---|---|
| Z | Launch into the air and unleash a flurry of strikes forward | ~31 Billion |
| X | Fly up high and crash down with a red strike | ~44 Billion |
| C | Slash forward repeatedly with tentacles, then release a burst | ~84 Billion |
| V | Create a red zone around you and deal AoE damage | ~202 Billion |
| F | Create a red zone around you and deal AoE damage longer than V move | ~1 Trillion |
How to Unlock F Move (Mastery Quest Line)
After you obtain the Black Reaper melee, you can start the mastery quest line that unlocks the F move. To begin, head back to Isolation Island and look for the Reaper Master NPC on top of the dome inside the building. Talking to them starts the Black Reaper mastery quest line, which has three quests in total.

Quest 1: Defeat 25 Black Reaper Bosses on Medium
The first quest asks you to defeat 25 Black Reaper bosses on Medium difficulty. It is not a hard quest, but it does eat through Reaper Keys fast. You will need around 50 Reaper Keys total to clear it.
Quest 2: Get the Ghoul Bloodline
The second quest is to roll the Ghoul bloodline. Open your settings, double-check that your bloodline auto reroll options are set up correctly, then keep using Bloodline Stones until Ghoul shows up.
Quest 3: Reach Mastery 250 on Black Reaper
The third quest is where most players spend the most time. You need to push Black Reaper to mastery 250. You can try doing raids for this. One Minotaur kill counts as 100 kills toward mastery progress.
Once you complete the final quest, you unlock the F move and also get a +30% damage buff for the Black Reaper melee.
The Black Reaper Melee is a solid pick in Sailor Piece right now, especially for boss content where the V move's area damage really shines. If you are grinding Sea content and want a melee that actually holds up, this one is worth going after.
