If you’ve been playing Sailor Piece, you already know one thing very clearly…Gems are everything.
From rerolling stats to summoning bosses and unlocking powerful items, gems are used in almost every major progression system. While the game does give you gems from multiple sources, farming them efficiently is what separates casual players from fast progress players.
In this guide, I’ll break down the fastest ways to farm gems in Sailor Piece, along with strategies that actually help you stack thousands instead of grinding randomly.
Best Ways to Farm Gems in Sailor Piece
Sailor Piece is designed in a way where almost every activity gives gems, but not all methods are equally efficient. Some methods give slow and steady gains, while others can multiply your farming speed.
1. Farming NPC Mobs (Best Method Overall)
The most consistent and reliable way to farm gems is by defeating NPC mobs.
As you move to higher-level islands, the gem rewards increase significantly. Early game mobs may give small amounts, but late-game areas can stack gems very quickly.
Best NPC Farming Strategy
| Factor | Recommendation |
|---|---|
| Location | High-level islands like Shinjuku or beyond |
| Build | High damage / AoE builds |
| Clan | Yamato or Zoldyck (for better farming efficiency) |
| Goal | Fast wave clearing |
Instead of focusing on single enemies, aim to clear groups quickly. The faster you wipe mobs, the faster your gem income increases.
2. Treasure Chests (High Reward Method)
Treasure chests are one of the most underrated ways to farm gems.
They drop from:
- NPC mobs
- Bosses
- Quests
- Codes
Higher rarity chests give significantly more gems.
Chest Rewards Overview
| Chest Type | Reward Potential |
|---|---|
| Common | Low gems |
| Rare | Moderate gems |
| Epic | High gems |
| Mythical | Very high gems |
| Secret | Massive gem rewards |
Farming in higher-level zones increases your chances of getting better chests.
3. Recurring Quests (Double Rewards Strategy)
If you are farming mobs without taking quests, you are missing out on easy extra gems.
Recurring quests allow you to earn:
- Gems from mobs
- Gems from quest completion
This effectively doubles your rewards for the same effort.
Why Quests Matter
| Benefit | Result |
|---|---|
| Extra rewards | More gems per run |
| Passive farming | No extra effort needed |
| Fast stacking | Works alongside mob farming |
Always pick up a quest before starting any farming session.
4. Dungeons and Infinite Tower
Dungeons are one of the best ways to farm gems in bulk, especially if you can clear them quickly.
Each dungeon run includes:
- Multiple waves
- Mini-bosses
- Final boss rewards
Similarly, the Infinite Tower is designed for continuous wave clearing, making it a great source of gems over time.
Dungeon Farming Breakdown
| Mode | Difficulty | Reward Potential |
|---|---|---|
| Normal Dungeons | Easy | Moderate |
| Double Dungeons | Medium | High |
| Rune Dungeons | Hard | Very high |
| Infinite Tower | Scaling | Continuous gems |
If your build is strong enough, this becomes one of the fastest farming methods in the game.
5. Boss Farming and Boss Rush
Bosses drop a large amount of gems compared to normal mobs, making them a key part of any farming strategy.
You can farm bosses in:
- Open world locations
- Dungeons
- Boss Island
Best Boss Farming Locations
| Location | Difficulty | Rewards |
|---|---|---|
| Sailor Island | Easy | Low |
| Shibuya Station | Medium | Moderate |
| Judgement Island | Hard | High |
| Boss Island | Very Hard | Very high |
To maximize efficiency, use a high damage build so you can defeat bosses quickly and repeatedly.
6. Redeeming Codes (Instant Gems)
Codes are the easiest way to get free gems without any grinding.
While not every code gives gems, some provide:
- Direct gem rewards
- Treasure chests (which contain gems)
Code Rewards Overview
| Reward Type | Benefit |
|---|---|
| Gems | Instant boost |
| Chests | Extra farming value |
| Boosts | Faster grinding |
Always redeem codes as soon as they are released.
7. Artifact Milestones (Passive Income)
Artifact farming is not just for power upgrades. It also gives gem rewards at certain milestones.
You can claim these rewards from specific NPCs after reaching certain levels.
Artifact Rewards
| Milestone | Reward |
|---|---|
| Early Levels | Small gem rewards |
| Mid Levels | Chests + gems |
| High Levels | Large gem payouts |
This is a passive method, but over time it adds up significantly.

How to Use Gems in Sailor Piece
Once you start farming gems, the next question is where to spend them wisely.
Gems are used in multiple systems, and spending them incorrectly can slow your progress.
Main Uses of Gems
| Use | Purpose |
|---|---|
| Weapons & Fighting Styles | Unlock stronger gear |
| Stat Rerolls | Optimize your build |
| Boss Summoning | Farm rare drops |
| Fruit Gacha | Get powerful fruits |
| Merchant Shop | Buy special items |
Best Way to Spend Gems (Beginner to Pro Strategy)
Instead of spending gems randomly, follow this approach:
- Early Game: Focus on weapons and upgrades
- Mid Game: Save gems for better builds
- Late Game: Invest heavily in stat rerolls and boss farming
Avoid wasting gems on unnecessary rerolls early on.
Fastest Gem Farming Strategy (Recommended Combo)
If you want the absolute fastest method, combine multiple systems together.
Optimal Farming Combo
| Step | Action |
|---|---|
| 1 | Take recurring quest |
| 2 | Farm high-level NPC mobs |
| 3 | Collect treasure chests |
| 4 | Run dungeons or towers |
| 5 | Kill bosses in between |
This layered approach ensures you earn gems from multiple sources at the same time.
