Best Weapon for Crystal Defense in Sailor Piece (Farming Guide)

Farming in Sailor Piece can feel slow even if your stats are already decent. In many cases, the real problem is not your build, but the weapon or spec you are using. Some weapons are simply much better at clearing waves, controlling space, and keeping damage consistent, especially in modes like Crystal Defense. This guide breaks down the best weapons for farming, with a focus on Crystal Defense, so you know exactly what to use and why.


Best Weapon for Crystal Defense

In Crystal Defense, your goal is simple: clear enemies as fast and consistently as possible. This means you need a weapon with strong area damage, good cooldowns, and reliable uptime. Weapons that deal damage nonstop or hit large areas will always outperform those with high burst but long downtime. That is why some weapons rank much higher even if their raw damage looks similar on paper. If your main goal is to farm Crystal Defense, Cosmic Being is easily the best choice right now. It offers:

  • Continuous damage with almost no downtime
  • High overall DPS
  • Strong performance in long wave-based modes

Ice Queen is a close second and works well if you do not have access to Cosmic Being yet.


Top 5 Best Weapons for Farming

5. Strongest of Today

This weapon is a solid choice if you want good damage with wide coverage. Its F move has strong range and can hit multiple enemies at once, making it useful in dungeons and boss rush. The downside is cooldown. You may find yourself waiting between attacks, which slows down your overall farming speed in long runs like Crystal Defense.

4. King of Heroes

King of Heroes remains one of the most practical farming weapons. It has a large attack range, smooth animations, and a reliable cooldown. It works well across different modes, including general farming and dungeons. While it does not have the highest damage output compared to newer options, it is very consistent and easy to use.

3. The World

This is one of the newer weapons and quickly became a strong all-around option. It offers high damage, large range, and smooth skill usage. The World is great for clearing waves quickly and works well in most game modes. It is a reliable choice if you want one weapon that can handle almost everything.

2. Ice Queen

Ice Queen has stayed near the top for a long time, and for good reason. It combines strong damage, wide range, and consistent performance. This weapon shines in multiple modes, including Crystal Defense, boss fights, and sea events. If you want a safe and reliable option that works everywhere, Ice Queen is one of the best picks.

1. Cosmic Being (Best for Crystal Defense)

Cosmic Being takes the top spot for one simple reason: nonstop damage. Its cooldown is very close to its animation time, which means you can keep attacking almost without pause. This creates constant pressure on enemies, making it perfect for long farming sessions. In Crystal Defense, where waves keep coming, this consistency is extremely important. You can clear enemies faster, maintain control, and farm more efficiently compared to other weapons.


Choosing the right weapon can completely change how fast you farm in Sailor Piece. Instead of focusing only on stats, it is better to use weapons that offer consistent damage and good area control. For Crystal Defense, consistency is everything. That is why Cosmic Being stands above the rest. If you want faster clears and smoother farming, switching to the right weapon will make a noticeable difference right away.
