The Ghoul update in Sailor Piece adds a lot of reasons to log in, grind, and check every corner of the map. The headline reward is Black Reaper, but the update also brings a new boss, a mastery system, new cosmetics, new auras, and a hidden progression path tied to a Blood Flower quest.

If you want a simple roadmap for what to do first, this guide breaks down the update in a player-friendly way so you can work toward the new rewards without wasting time.

What the Ghoul update adds

Here’s a quick overview of the main content players can check out in-game:

FeatureWhat it doesWhy it matters
Black ReaperNew melee weaponMain highlight of the update
New bossBoss fight tied to progressionNeeded for update quests and rewards
Mastery systemWeapon-based progressionEncourages grinding with specific weapons
Blood Flower QuestHidden quest line for the new islandUnlocks access to new content
New aurasCosmetic rewardsExtra collectibles for aura hunters
New cosmeticsAdditional visual itemsCompletionist content
Title accessoryNew update-themed itemA goal for collectors

A big part of the update is that it gives you a reason to specialize. Instead of leveling whatever is closest, the new mastery system pushes you to use one weapon consistently.

How to start the Blood Flower quest

The update’s hidden island progression begins with the Blood Flower Quest. In-game, you can start it from the new NPC tied to the quest line.

The objective is straightforward:

  1. Talk to the Blood Flower quest NPC.
  2. Find the hidden blood flowers around the world.
  3. Return to the NPC after collecting all of them.

The flowers are spread across different islands, so don’t assume they’re all in one place. Players may need to travel island by island and check common hiding spots like cliffs, trees, island edges, and landmark areas.

Practical search tips

Where to lookWhy it helps
Behind islandsEasy place for hidden pickups
Near large landmarksQuest items often spawn around visible points
Around trees and rocksGood for objects tucked into corners
By island hubsFast to check while traveling between zones

Since hidden quest items can be easy to miss, it helps to move in a consistent route and check each island carefully before leaving.

How Black Reaper fits into the update

Black Reaper is the update’s big reward and the reason many players are grinding the new content. It is a melee weapon, and it appears to be built around a flashy, Ghoul-themed attack style.

The weapon can be obtained through the update’s progression, and there is also a Reaper key requirement tied to the Black Reaper content area. Players should expect to spend time farming enemies and running the boss content connected to the weapon.

What makes it worth unlocking

Black Reaper stands out because it:

  • Has a distinct visual style
  • Fits the Ghoul theme of the update
  • Comes with a progression track of its own
  • Benefits from mastery upgrades
  • Feels stronger once your build supports melee damage

If you prefer melee-focused loadouts, this is one of the most important additions in the update.

Black Reaper mastery explained

The update introduces a mastery system that rewards repeated use of a weapon. For Black Reaper, mastery is tied to kills with that weapon.

The player-facing idea is simple:

  • Use the weapon you want to level
  • Defeat enemies with it
  • Claim mastery rewards as you unlock them

One important detail: mastery rewards do not appear to auto-claim. You need to check the mastery menu and press the claim button when a reward is ready.

Black Reaper mastery at a glance

Mastery levelReward effect
Early levelsSmall combat upgrades
Mid levelsDamage-related bonuses and progression perks
Higher levelsStronger combat value for the weapon
500 masteryA chance-based damage boost is shown in the mastery track

The exact feel of the weapon changes as mastery rises, so it’s smart to keep an eye on the menu while grinding.

Best way to grind Black Reaper mastery

If you want to push mastery efficiently, focus on enemies you can defeat quickly and consistently. The key is to maximize kills per minute rather than chasing a tougher target you can barely finish.

Better mastery grind habits

  • Stay on a weapon build that can clear enemies fast
  • Use areas where enemies respawn quickly
  • Check mastery progress often so you can claim upgrades
  • Avoid letting reward claims sit unclaimed
  • Keep farming until you hit the next breakpoint

A small improvement in clear speed can save a lot of time over a long grind.

New boss and Reaper Keys

The update also adds a new boss encounter connected to Black Reaper content. Players need Reaper Keys to access that boss, and the fight is tied to update progression.

From a practical standpoint, this means your routine will likely include:

  • Farming enemies for keys
  • Spending keys on boss runs
  • Repeating the boss to finish unlock requirements
  • Returning to the Black Reaper room once you have enough progress

The boss can be used as a targeted farm if you want to push update rewards instead of wandering the map randomly.

Boss farming checklist

GoalWhat to do
Get keysFarm enemies in the relevant area
Clear the bossUse your strongest available build
Finish unlocksRepeat runs until your quest is complete
Save timeUse fast-mobility or high-uptime damage

If your damage feels low, check your build before you commit to a long farming session.

How to improve damage for the update

This update favors players who tune their builds around the weapon they actually want to use. If Black Reaper is your goal, you’ll likely want to focus on melee-friendly choices and damage multipliers.

The player-tested approach is to look at:

  • Race bonuses
  • Clan bonuses
  • Bloodline bonuses
  • Accessory bonuses
  • Weapon type scaling

You may not need the absolute best setup to get started, but your damage will rise a lot once your build starts working with the weapon instead of against it.

Build planning table

Build slotWhat to look for
RaceDamage or melee support
ClanStats that fit your chosen attack style
BloodlineBonuses that improve your main damage type
AccessoryExtra combat value or utility
WeaponMatch the weapon to the rest of the build

If you’re unsure where to start, test your current loadout on the Black Reaper boss and compare how long each kill takes.

New cosmetics and auras

The Ghoul update also includes new cosmetics and two new auras. These are the kind of rewards collectors and fashion-focused players usually care about most.

The update appears to include crate-style rewards, so results may vary and some drops can feel random. If you’re hunting visuals, expect some trial and error.

What to know about cosmetic chasing

  • Crates can be luck-based
  • Some items may be rarer than others
  • You may need several rolls before seeing the item you want
  • Cosmetics are a good side goal while grinding mastery or boss keys

If you’re already farming the update’s core content, treat cosmetics as a bonus instead of the main objective.

Is Black Reaper worth using?

For players who enjoy melee combat and flashy skills, yes—Black Reaper is absolutely worth checking out. It has strong visual identity, and it feels especially satisfying once you start stacking mastery and the rest of your build around it.

That said, it is still smart to compare it against your current weapon and setup. Some players may get better results from a fully tuned sword build or another damage-focused loadout, depending on where they are in progression.
