Sailor Piece is a Roblox One Piece RPG where late-game progression demands some seriously rare materials. The Soul Flame is one of the most sought-after Mythical-rarity items in the game, required for unlocking the Soul Reaper Sword and advancing through Ascension Level 6. It only drops from one source, carries a brutal drop rate, and cannot be found anywhere on the open map. However, with the right setup and strategy, you can farm it efficiently without burning out.

What Is Soul Flame in Sailor Piece?
Soul Flame is a Mythical-rarity item and one of the rarest drops in Sailor Piece, serving as a core material for two major late-game unlocks: the Soul Reaper Sword and Ascension Level 6. You cannot find it on any island or purchase it from any NPC. The only two ways to obtain it are by defeating the Soul Reaper (Ichigo) Boss on Boss Island, or by trading with another player who already has one. There are no confirmed codes or limited-time events that reward Soul Flame directly.
How to Get Soul Flame in Sailor Piece
The Soul Reaper Boss does not appear anywhere on the Sailor Piece map by default. You need to summon it manually through the Boss Summoner NPC on Boss Island. Here is the full step-by-step process:
Step 1: Use any nearby portal to travel to Boss Island.
Step 2: Locate and speak to the Boss Summoner NPC to open the summon window.
Step 3: Scroll through the boss list and select Soul Reaper (Ichigo).
Step 4: Confirm you have the required materials in your inventory before summoning.
Summon Requirements
| Requirement | Amount |
| Boss Keys | 5x |
| Cash | 350,000 |
| Gems | 600 |
Step 5: Once the boss spawns, head to the centre of the island and begin the fight. You need to deal at least 10% of the Soul Reaper’s 65 million HP to qualify for any rewards. Staying active throughout the entire fight is essential, as letting others carry the damage means you walk away with nothing.
Because the Soul Reaper is a Boss Island spawn rather than a timed island boss, you can repeat the summon as many times as you have materials available. This makes consistent farming far more manageable compared to waiting on respawn timers.
How to Farm Boss Keys
Boss Keys are the biggest early bottleneck for Soul Flame farming, since each Soul Reaper summon costs 5x. Stockpiling them before you begin your Ichigo grind is strongly recommended. Here are all the confirmed methods to obtain Boss Keys in Sailor Piece:
Defeating Regular NPCs and Mini-Bosses: Boss Keys drop from standard mobs and mini-bosses across the game. Higher-level enemies carry slightly better drop chances. Players commonly farm dense, high-level packs on advanced islands using AoE-heavy builds for fast accumulation.
Completing Quests: Main story and Quest NPCs reward Boss Keys as part of their completion rewards. There are around ten notable Quest NPCs on the starting islands, and working through their questlines is one of the most reliable early methods.
Opening Chests: Chests dropped by enemies can contain Boss Keys. Higher Luck improves both the quality and frequency of chest drops, so building your Luck stat before chest farming pays off.
Merchant NPC on Sailor Island: You can buy Boss Keys directly from the Merchant NPC on Sailor Island. The shop refreshes every 30 minutes, making it a reliable passive supplement to active farming.
For early-to-mid game players, combining quest completion with regular mob farming covers Boss Key needs steadily. Late-game players can one-shot high-level mobs for fast accumulation. Either way, building a stock of 20 to 30 Boss Keys before starting your Soul Flame farm sessions removes one of the biggest interruptions to your grinding rhythm.
Soul Flame Drop Rate and Full Ichigo Loot Table
The Soul Flame has a confirmed drop rate of 0.70% to 0.77%, making it the rarest item in the Soul Reaper’s entire loot pool. Most players need many runs before their first Soul Flame drops, and there is no confirmed pity system or guaranteed drop after a set number of attempts. Planning for a long grind is realistic, even with a maxed Luck build.
However, every Ichigo run also provides progress toward other valuable goals. The full confirmed loot table makes each run worthwhile beyond just chasing Soul Flame.
Full Soul Reaper (Ichigo) Boss Loot Table
| Drop | Drop Rate | Notes |
| Boss Ticket | 100% | Useful for alternative unlocks or trading |
| Haki Color Reroll | 85% | Very common reroll item |
| Race Reroll | 80% | Common |
| Trait Reroll | 60% | Common |
| Dungeon Key | 20% | For Rune Dungeon access |
| Soul Fragment | 6% | Required for Soul Reaper Sword |
| Hollow Mask (Accessory) | 2% | Cosmetic with possible minor stats |
| Spiritual Core | 1.75% | Required for Soul Reaper Sword |
| Soul Reaper (Title) | 1% | Title with potential minor bonuses |
| Soul Flame | 0.70% to 0.77% | Rarest item in the pool |
Every run contributes Haki rerolls, Race rerolls, Dungeon Keys, and sword materials alongside your Soul Flame attempts, making the Ichigo grind one of the most rewarding farming loops in the game even when Soul Flame does not drop.
How to Farm Soul Flame Efficiently
Build for Maximum Damage Output
Every boss fight in Sailor Piece requires you to deal at least 10% of the boss’s HP, so arriving with a strong build is non-negotiable. The Soul Reaper has 65 million HP, which means you need to contribute at least 6.5 million damage to qualify for rewards. Aim for Level 5,000 or above before starting your Ichigo farm, and combine your best sword, fighting style, and devil fruit to maximise damage output. Faster boss clears also mean more runs per session, which directly increases your Soul Flame chances over time.
Stack Your Luck Before Farming
Luck directly influences rare item drop rates, and at a base rate of 0.70%, every percentage point matters. Here are all confirmed Luck-boosting methods:
| Method | Luck Bonus |
| Fortune Rune (from Rune Dungeon) | +10% to +15% Luck |
| Monarch, Pride, or Espada Clan | +10% Luck each |
| Kitsune Species Reroll | +25% overall Luck |
| Destiny Mark Title (defeat 2,500 bosses) | +40% Luck |
| Lucky Titles (Lucky Novice, Fortune Seeker, Lucky Star, Blessed One, The Chosen One, Blessed Sovereign, Destiny Marked) | Varies |
| 2x Luck Weekend Event | 2x global Luck |
| 3x Luck Weekend Event | 3x global Luck |
The weekly Luck Weekend events offering 2x or 3x global Luck are the single most impactful windows for Soul Flame farming. Timing your heaviest grind sessions around these events can cut your required run count significantly. Check in-game announcements so you do not miss them.
Team Up for Faster Clears
Soloing the Soul Reaper is possible but slower, and reaching the 10% damage threshold is easier with teammates dealing consistent damage alongside you. Coordinating with a small group all farming Soul Flame at the same time keeps runs fast and efficient.
Server Hop to Eliminate Downtime
After each boss run, rather than waiting on the same server, hop to a new one and look for active Soul Reaper summons already in progress. Server hopping removes the bulk of downtime between attempts and keeps your runs-per-hour count high.
Can You Trade Soul Flame?
Yes, Soul Flame is fully tradeable with other players. Because of its Mythical rarity and low drop rate, other players will expect something of equivalent value in return. Lowball offers tend to get declined, so knowing the current going rate on your server before approaching a trade is worth taking a moment to check. Trading works best as a supplement to farming rather than a full replacement.
All Soul Flame Uses in Sailor Piece
1. Soul Reaper Sword
The primary reason most players farm Soul Flame is to unlock the Soul Reaper Sword. The Soul Reaper NPC (also called the Ichigo NPC) is on Hueco Mundo Island (Hollow Island), located past the tilted building near the edge of the island. Interact with the NPC and submit all required materials to receive the sword.
The Soul Reaper Sword delivers long-range attacks with a distinctive blood-red animation, making it a strong mid-to-late game weapon. Notably, every single material required for the sword drops from the Ichigo Boss itself, so one focused farming session covers the sword requirements and Soul Flame simultaneously.
Soul Reaper Sword Requirements
| Requirement | Amount | Drop Rate (from Ichigo) |
| Soul Flame | 2x | 0.70% to 0.77% |
| Spiritual Core | 4x | 1.75% |
| Soul Fragments | 8x | 6.00% |
| Gems | 8,500 | In-game currency |
| Cash | 5,000,000 | In-game currency |
2. Ascension Level 6
Soul Flame is also a required material for Ascension Level 6, one of the most demanding progression milestones in Sailor Piece. Ascension 6 grants permanent buffs to your character, making the investment worthwhile for any serious long-term build.
Ascension Level 6 Full Requirements
| Requirement | Amount |
| Soul Flame | 3x |
| Blood Ring (drops from Alucard Boss at approx. 2%) | 3x |
| Character Level | 8,500 |
| NPC Kills | 850 |
| Boss Kills | 250 |
| Total Damage Dealt | 20 billion |
| Abilities Used | 850 |
| Rune Dungeon (Medium) Cleared | 10 times |
| Shadow Dungeon (Medium) Cleared | 5 times |
Ascension Level 6 Buffs
| Buff | Amount |
| Gems earned | +10% |
| Cash/Money earned | +10% |
| Luck | +5% |
Given that Ascension 6 requires 3x Soul Flames on top of the 2x needed for the sword, planning to farm at least 5 Soul Flames in total from the start is the most efficient approach. Extras also give you trading stock or a buffer against bad RNG on future upgrades.
