How to Get Moon Cut Katana in Broken Blade Guide
Moon Cut is currently one of the most popular Katana weapons in Broken Blade. Many players consider it one of the best choices for progressing through the late game because it is easier to obtain than some endgame weapons while still providing excellent damage and farming potential.
Although getting Moon Cut requires a fair amount of grinding, the process is much more manageable compared to weapons like Excalibur or Dragon Slayer. If you’re planning to build around Katanas, Moon Cut should be one of your primary goals.
What is Moon Cut & How to Get?

Moon Cut is a powerful Katana weapon that offers strong damage and efficient boss farming capabilities. Its accessibility and effectiveness make it a favorite among players who want a reliable weapon without investing massive amounts of resources into rarer alternatives. Many experienced players continue using Moon Cut even in the later stages of the game because of its solid performance and relatively straightforward farming process.
1. Travel to Nidavellir
To begin farming Moon Cut, you need to head to Nidavellir. This area contains the Colosseum where players can summon special bosses. These bosses drop the materials required to unlock the weapon. Before starting the grind, make sure you have a good amount of Boss Keys available since they are required to summon enemies inside the arena.
2. Collect 100 Moon Pieces
The main requirement for unlocking Moon Cut is obtaining 100 Moon Pieces. Moon Pieces are dropped by bosses inside the Nidavellir Colosseum. After summoning and defeating these bosses, you’ll have a chance to receive Moon Pieces as part of the reward pool.
Once you collect enough pieces, you’ll be able to exchange them for the Moon Cut Katana. The grind can take some time, but it is currently the primary method for obtaining the weapon.
Best Boss to Farm for Moon Pieces
Many players recommend farming Niveron when collecting Moon Pieces. Niveron is considered one of the easiest bosses to defeat consistently, making it an efficient choice for long farming sessions. Since the boss can be cleared quickly, players can gather Moon Pieces faster than attempting more difficult encounters. If your damage is still developing, Niveron is often the safest option.
Use Luck Boosts Whenever Possible
Luck bonuses can significantly improve your farming efficiency. Using titles or boosts that increase Luck will improve your chances of receiving Moon Pieces from boss rewards. While the difference may not seem huge at first, the extra drop rate becomes very noticeable over dozens of boss runs. Players who use Luck bonuses generally complete the Moon Cut grind much faster.
Upgrade Moon Cut After Unlocking It
Obtaining Moon Cut is only the first step. To maximize its potential, you’ll want to upgrade the weapon as much as possible. Visit the weapon upgrade NPC and invest materials into your Katana. For most players, Diamond materials are a great choice because they provide critical damage bonuses. Critical damage plays a major role in increasing your overall damage output, making Diamond upgrades one of the most efficient investments available.
Farm Soul Stones for Additional Power
After upgrading Moon Cut, you should focus on gathering Soul Stones. One of the best ways to do this is by running Sky Spire and participating in other endgame activities. Soul Stones can be used at the Soul Forge to further enhance your weapon and increase your damage. The stronger your Moon Cut becomes, the easier it will be to farm bosses, clear towers, and prepare for future content.
Why Moon Cut is Worth Getting
There are several reasons why Moon Cut remains one of the most recommended weapons in Broken Blade:
- Easier to obtain than many endgame weapons
- Strong damage output
- Excellent for boss farming
- Effective throughout most stages of progression
- Works well with Katana-focused builds
For players who enjoy using Katanas, Moon Cut offers one of the best combinations of power and accessibility.
Moon Cut is one of the strongest Katana weapons currently available in Broken Blade. While collecting 100 Moon Pieces requires dedication, the reward is well worth the effort. By farming bosses in Nidavellir, using Luck bonuses, and upgrading the weapon properly, you can unlock a powerful Katana that remains useful well into the endgame. If you’re deciding between different weapon paths, Moon Cut is often one of the safest and most efficient choices for long-term progression.
