What to know
- Crystal Relics are obtained from the Crystal Defense Raid on Punch Island.
- You need a Crystal Key to access the Crystal Defense Portal.
- Bosses appear every fifth wave and can drop Crystal Damage or Crystal Luck Relics.
- The relic drop rate is low, so expect to repeat the raid multiple times.
If you are trying to improve your farming efficiency or overall combat power in Sailor Piece, Crystal Relics are among the most useful items you can target. These relics provide specialized bonuses that help either with raw damage output or increasing luck-based rewards. Although the process to unlock them is simple, actually obtaining them can take patience because of the low drop chances tied to the raid bosses.
Here is a quick overview of Crystal Relics in Sailor Piece:
| Feature | Details |
|---|---|
| Relic Types | Crystal Damage Relic, Crystal Luck Relic |
| Location | Punch Island |
| Required Item | Crystal Key |
| Activity Type | Crystal Defense Raid |
| Boss Spawn Timing | Every 5 waves |
| Main Objective | Survive enemy waves and defeat bosses |
| Difficulty | Moderate to High |
| Drop Chance | Low |
Where the Crystal Defense Raid takes place
The entire Crystal Relic farming process revolves around Punch Island, which is where the Crystal Defense Portal NPC can be found. Once you arrive on the island, you will need to interact with the NPC to begin the raid activity. The portal cannot be opened for free, so make sure you already have a Crystal Key before heading there.

Since the raid involves multiple enemy waves and recurring boss fights, it is recommended to bring your strongest build or farm alongside other players if possible.
How to unlock Crystal Relics in Sailor Piece
Getting Crystal Relics mainly comes down to repeatedly clearing the Crystal Defense Raid and hoping for the correct drop reward from the boss enemies.
The raid is a wave-defense style activity where enemies continuously spawn in increasing difficulty levels. Every fifth wave introduces a boss encounter, and these bosses are the only enemies capable of dropping Crystal Relics.
The two relics currently available from this activity are:
| Relic | Main Effect |
|---|---|
| Crystal Damage Relic | Boosts damage output |
| Crystal Luck Relic | Improves luck-related bonuses and drops |
Because both relics share the same loot pool, farming for a specific one may require multiple clears.
How to get Crystal Relics in Sailor Piece
Step 1
Travel to Punch Island in Sailor Piece. This island contains the Crystal Defense activity and its associated NPC.
Step 2
Locate and speak to the Crystal Defense Portal NPC. This NPC is responsible for opening the raid portal.

Step 3
Use one Crystal Key to activate the portal. Without this item, you cannot enter the raid instance.

Step 4
Enter the Crystal Defense Raid and begin clearing enemy waves. The difficulty increases steadily as more enemies spawn.

Step 5
Defeat the boss that appears every fifth wave. These bosses are your source for Crystal Relic drops.
Step 6
Check your rewards after defeating the boss. You have a chance to obtain either the Crystal Damage Relic or the Crystal Luck Relic.

Crystal Damage Relic explained
The Crystal Damage Relic is designed for players focused on maximizing combat performance. It increases your offensive potential, making it especially useful for:
- Boss farming
- Fast NPC clearing
- Raid progression
- PvE grinding
- Higher DPS builds
Players using sword-focused or fruit-heavy damage builds will likely see the biggest benefit from equipping this relic.
Crystal Luck Relic explained
The Crystal Luck Relic focuses more on improving luck-related mechanics. While exact scaling may vary depending on updates, luck bonuses in Sailor Piece generally help improve farming efficiency and reward outcomes.
Many players farm the Luck Relic first because it can indirectly help improve future farming sessions.
Best farming strategy for Crystal Relics
Since the biggest obstacle is the low drop rate, efficiency matters more than raw difficulty. Running the raid quickly and consistently is the best long-term approach.
Here are the most effective methods players currently use:
| Strategy | Why It Helps |
|---|---|
| Farm with teammates | Faster wave clearing |
| Use high AoE abilities | Clears mobs quickly |
| Stockpile Crystal Keys | Reduces downtime |
| Focus boss damage | Speeds up completion |
| Repeat lower-risk runs | Better farming consistency |
If you are underleveled, avoid pushing too far into difficult waves and instead prioritize consistent completions.
Crystal Relic farming tips for beginners
Newer players often struggle because they enter the raid without proper preparation. A few simple adjustments can make farming much smoother.
| Tip | Benefit |
|---|---|
| Bring healing items | Improves survivability |
| Upgrade your weapon first | Faster wave clears |
| Save keys before farming | Allows longer sessions |
| Play during active servers | Easier team farming |
| Focus mobility skills | Helps avoid damage |
Patience is the most important factor. Some players obtain a relic quickly, while others may need many attempts before seeing a drop.
Crystal Relics are among the better long-term upgrades you can farm in Sailor Piece, especially if you regularly participate in raids and boss content. The process itself is simple: enter the Crystal Defense Raid on Punch Island, survive the enemy waves, defeat bosses, and keep farming until the relic drops. While the low drop rate can make the grind lengthy, the bonuses from both the Crystal Damage Relic and Crystal Luck Relic make the effort worthwhile for progression-focused players.
