The latest Sailor Piece update added several new grinding systems, and many players are now focusing on farming Reaper Keys, Black Reaper materials, and the brand-new Ghoul Aura. Because many of the new drops have extremely low rates, having a proper farming setup is now more important than ever. Players who use a full luck build can farm much faster and save a huge amount of time compared to normal builds.
The Ghoul Aura is one of the most wanted rewards in the update, but getting it is not easy. It drops from the Black Reaper Boss, which requires Reaper Keys to summon. Since the keys themselves already have a low drop chance, players need to optimize their farming route if they want to collect the new rewards efficiently.

How to Get Reaper Keys in Sailor Piece
Reaper Keys are currently one of the most important items in the game because they are required to access the new Black Reaper boss fight. These keys drop from Ghoul Members found on Isolation Island.
The problem is that the drop rate is very low. Because of this, players are strongly recommended to use a full luck-focused farming build while grinding enemies. Without proper luck bonuses, farming keys can take much longer. Isolation Island is currently the main farming location for players preparing for the Black Reaper update content.
How to Get Ghoul Aura
The Ghoul Aura drops from the Black Reaper Boss. This boss is considered the center of the entire update because it provides almost every important new item tied to the Black Reaper progression route. Besides the Ghoul Aura, the boss can also drop:
- Black Reaper melee materials
- Ghoul Outfit
- OneEyed King title
- Other rare farming rewards
The OneEyed King title is currently one of the strongest damage titles in the game because it gives around +110% damage. Meanwhile, the Ghoul Outfit is also considered one of the best accessories available thanks to its massive stats.
At maximum enchantment level, the Ghoul Outfit provides:
- +155% Damage
- +185% Defense
- +35% Damage Reduction
Because of these rewards, many players are repeatedly farming the Black Reaper Boss even after unlocking the Ghoul Aura.
Best Difficulty for Black Reaper Farming
Even though higher difficulties slightly improve drop chances, Easy difficulty is still considered the best option for farming efficiently. Here is the Reaper Key cost for each difficulty:
- Easy 1 Key
- Medium 2 Keys
- Hard 3 Keys
- Extreme 4 Keys
The higher modes may offer slightly better rewards, but the increase is usually not large enough to justify spending extra keys. Most players can complete Easy runs faster while saving more keys overall, making it the better long-term farming route.
Best Updated Luck Build in Sailor Piece
The newest update made luck builds much stronger because Mastery bonuses and new systems now affect farming efficiency even more than before. Here is the recommended updated luck build setup:
Best Rune
Use the fully upgraded Radiant Rune. This rune still provides one of the highest luck bonuses in the game with around +28% Luck. Infinity Tower is also important because it gives permanent luck upgrades while farming runes.
Best Spec Passives
Players should use:
- Fortune Chosen on the main weapon
- Luck V on the secondary weapon
Fortune Chosen gives visible luck bonuses and additional drop effects, while Luck V pushes your total luck even higher.
Best Power and Relic
Recommended setup:
- Subjugator Power
- Crystal Luck Relic
Subjugator remains one of the best farming powers because it gives strong luck bonuses while still helping with combat performance.
The Crystal Luck Relic also remains one of the strongest relics for farming thanks to its +30% Luck bonus.
Best Race, Clan, and Bloodline
For the current meta farming setup, players should use:
- Race: Archangel
- Clan: Devil
- Bloodline: Ghoul
Archangel gives large luck bonuses and increased double drop chance. Devil Clan also improves farming value.
The biggest change is the Ghoul Bloodline, which is now considered the best farming bloodline in the game. It provides:
- +37% Damage
- +5% Damage Reduction
- +22% Luck Multiplier
- +12% Melee Damage
- +45% Max HP
- 20% Chance for Extra Drops
Because of these bonuses, Ghoul replaced Primordial as the top farming bloodline.
Why Mastery Is Important for Farming
Mastery became much more important after the update because players can now stack additional luck bonuses across different equipment types. Once you unlock the level 100 mastery reward on:
- Melee
- Sword
- Fruit
You can gain around +96% total extra luck combined.
Weapons at Mastery 500 also gain even stronger active mastery bonuses, making farming builds significantly stronger than before.
Best Index Progression Setup
Index progression is another major part of the new farming meta. Reaching higher index milestones gives permanent boosts including:
- +35% Damage
- +25% Luck
- +25% Crit Damage
- +3.5% Crit Chance
- +25% HP
Players are encouraged to push their index as high as possible because these bonuses make a noticeable difference during long farming sessions.
The Ghoul Aura update made Sailor Piece farming much more rewarding, but also much more demanding. Reaper Keys, Black Reaper materials, and other rare drops require a strong farming setup if players want to progress efficiently. By using a full luck build and farming the Black Reaper boss on Easy difficulty, players can save keys while maximizing their chances of obtaining the Ghoul Aura and other powerful rewards.
