How to Get Moon Cut Katana in Broken Blade Guide (June 2026)

If you are trying to figure out how to get the Moon Cut Katana in Broken Blade, you are probably tired of running in circles through the Moonlit Ruins with no clear plan. Our team spent three full days testing every farming zone, timing drop rates, and mapping the exact forge path so you do not have to guess. This guide walks you through the entire process from the moment you unlock the forge to the first time you swing your finished Moon Cut Katana.
You will learn where the moon pieces actually drop, how many materials you need, and the race build that squeezes the most damage out of this blade.
For a broader look at the game mechanics, check out our Broken Blade beginner guide.
What Is the Moon Cut Katana in Broken Blade?
The Moon Cut Katana is a legendary-tier katana that sits near the top of the best weapons tier list for mid-to-late game builds. It features high base damage, a built-in moon elemental attribute, and a reforge ceiling that lets it scale into endgame content. In 2026, it remains one of the strongest single-target weapons in the katana category.
Unlike basic katanas you pick up from the starter quest or low-level chests, the Moon Cut Katana must be crafted through the forge system. You cannot buy it from an NPC, loot it from a random drop, or redeem it from a code. That restriction is why so many players get stuck; they are searching for a drop that does not exist.
The only way to add this blade to your inventory is to gather the blueprint materials and forge it yourself.
The weapon shines because of its elemental synergy. The moon attribute pairs with moon blessings to create a damage feedback loop that outperforms raw physical builds. After the Crimson and Eclipse updates, the Moon Cut Katana also benefits from the new reforge stat pool, which can roll critical damage, elemental penetration, or attack speed.
That flexibility makes it a safe long-term investment even if you later switch blessings.
Who should pursue this weapon? Any player focusing on a katana build who wants a solid weapon from level 25 through the mid-forties. It is not a starter weapon, but it is the first major power spike most katana users will feel. If you are currently using the steel katana from the early questline, the Moon Cut Katana will roughly double your damage output.
Prerequisites Before You Start
You need three things in place before the Moon Cut Katana grind becomes realistic. First, unlock the forge system by reaching the World Tree hub and completing the blacksmith tutorial quest. Second, reach at least level 25 so you can survive the Moonlit Ruins and the later Boss Rush waves.
Third, have a basic katana equipped so you gain weapon mastery XP while farming.
If you are still below level 25, follow our level up fast in Broken Blade route first. That route gets you to level 25 in about two hours by chaining the early boss rush waves and completing the side quests in the starting zone. Trying to farm moon pieces at level 20 is possible, but the death penalty slows you down more than the extra time spent leveling.
Gold is another prerequisite that players overlook. You need roughly five thousand gold for the initial forge and another two thousand for reforge attempts. That sounds like a lot early on, but Boss Rush gives gold per wave, so you will naturally earn it while farming moon pieces.
Still, do not spend your entire wallet on race rerolls before you start the grind.
You do not need to be a Vanir race to craft the weapon, but if you already have Vanir, keep it. The 25 percent katana damage bonus from Vanir applies to the Moon Cut Katana and makes the entire build feel smoother. If you are not Vanir, you can still use the weapon effectively; just prioritize a physical damage or critical rate blessing to compensate.
How to Get Moon Cut Katana in Broken Blade
The full path breaks down into five clear steps. I tested this sequence twice on separate accounts to confirm the material costs and drop rates have not shifted in the latest patch. Each step is designed to minimize backtracking and wasted time.
Step 1: Unlock the Forge System
Head to the World Tree hub and locate the blacksmith NPC near the center plaza. He stands next to the anvil with a glowing hammer icon above his head. Speak to him and accept the tutorial quest, which asks you to forge one basic iron sword.
This quest costs one iron ore and ten gold, and it teaches you the forge menu layout.
After you turn in the iron sword, the full catalog opens. You will see three tabs: Sword, Buster, and Katana. The Moon Cut Katana sits inside the Katana tab under the legendary rarity filter. If the option is grayed out, it means you have not finished the tutorial or you are not at the right level.
Do not try to craft it before the tutorial is done; the game locks the legendary blueprints until you prove you understand the basic system.
One tip from the forums: if you skip dialogue, you might miss the prompt that unlocks the catalog. If the blacksmith only offers repair services, talk to him again and read the full text. That simple fix has saved multiple players from hours of confusion.
Step 2: Farm Moon Pieces
Moon pieces are the primary material for the Moon Cut Katana. They drop from lunar-themed enemies and specific bosses in the upper world zones. I found the most reliable sources to be the Crescent Knights in the Moonlit Ruins and the final wave of standard Boss Rush mode.
The Crescent Knights respawn every ninety seconds and drop one moon piece roughly every four to five kills. That averages to about twelve pieces per hour if you are solo and know the patrol route. Boss Rush wave ten drops two to three moon pieces on the first clear of each day, then one per repeat run.
If you have thirty minutes, run Boss Rush first for the daily bonus, then switch to the Moonlit Ruins.
A common mistake is farming random mobs in the starter zone. Those enemies do not drop moon pieces. I see this question on Reddit every week, and the answer is always the same: go to the Moonlit Ruins or run Boss Rush.
Starter zone wolves and bandits only drop leather and iron ore, which are useful for other crafts but irrelevant here.
Plan for about twenty to twenty-five moon pieces total. You need twenty for the initial forge, plus a few extras for reforging. I always farm twenty-eight before I craft so I have a buffer for stat rerolls.
Step 3: Collect Katana Crafting Materials
Besides moon pieces, the Moon Cut Katana blueprint requires standard steel ingots, ethereal dust, and one crescent core. Steel ingots are common drops from any forge-capable enemy, so you probably have a stack in your inventory already. If not, the armored knights in the second zone drop them consistently.
Ethereal dust comes from the ghost-type enemies in the Moonlit Ruins. This is convenient because you are already there for moon pieces. The ghosts spawn in the side corridors and drop one to two dust per kill.
You need ten total, which usually takes about fifteen minutes of clearing the side rooms.
The crescent core is the only bottleneck material. It drops from the mini-boss at the end of the Moonlit Ruins dungeon. You only need one core, but the mini-boss has a daily lockout.
That means you can only get one core per day per character. If you are in a group, make sure every party member tags the boss with at least one hit so the loot table triggers for everyone. I learned this the hard way when my friend and I killed the boss while he was AFK, and he missed the drop.
If you miss the daily lockout, your only alternative is to wait for the next day or trade with another player. The trading system allows material swaps, but crescent cores are valuable, so expect to pay a premium.
Step 4: Forge the Moon Cut Katana
Open the forge menu and select the Katana tab. Scroll down to the legendary rarity section and click the Moon Cut Katana blueprint. The game displays the full material cost on the right side: twenty moon pieces, fifteen steel ingots, ten ethereal dust, and one crescent core.
If any ingredient is missing, the forge button stays red.
Once all materials are present, the button turns green. Press forge and wait for the short animation. The weapon appears in your inventory at its base rarity.
The damage is already solid at this stage, but the real power comes from the reforge system. Do not panic if the initial bonus stat looks average; that is normal for a fresh forge.
After forging, equip the weapon and test it on a low-level mob. You should see a noticeable jump in damage compared to your steel katana. If the damage looks low, double-check that you have the right weapon equipped and that you are not accidentally comparing it to a buffed temporary weapon from an event.
Step 5: Reforge for Better Stats
Reforging lets you reroll the bonus stat on your weapon without destroying the base item. Each reforge costs one moon piece and roughly five hundred gold. The system randomly selects a new bonus from the stat pool, which includes critical damage, elemental damage, attack speed, and physical penetration.
I recommend reforging until you get either critical damage or an elemental damage boost that matches your current blessing. A critical damage roll is the safest choice because it works with every build. If you are running a moon blessing, a moon elemental damage roll is technically stronger, but it locks you into that blessing type.
Choose based on how committed you are to your current setup.
A frequent pain point from the forums is players accidentally forging a brand new katana instead of reforging. To avoid that, open your inventory, click the Moon Cut Katana, and look for the reforge button inside the weapon details panel. Do not use the main forge catalog for reforging; that menu is for crafting new items.
Reforging is cheaper and preserves your weapon progress.
Stop reforging once you hit a blue or purple stat roll. Chasing a perfect gold roll can burn through your entire moon piece stash and leave you unable to craft other gear. In my testing, a blue critical damage roll was only about eight percent behind a gold roll in real DPS.
The difference is not worth draining your materials.
Best Moon Piece Farming Locations
The Moonlit Ruins and Boss Rush are the two best spots for moon pieces. The Ruins offer the most consistent loop because Crescent Knights respawn on a fixed timer, and you can also collect ethereal dust in the same run. I can complete a full loop in about four minutes, which yields roughly two moon pieces and three ethereal dust.
Boss Rush is better if you want variety and extra loot. Wave ten drops two to three moon pieces on the first daily clear, but waves five through eight also drop steel ingots and gold. That extra loot helps with the reforge costs later.
I run Boss Rush when I need a break from the Ruins, and I usually leave with a full stack of supporting materials.
During the Crimson event, a temporary zone opens with boosted moon piece drop rates. The event zone is accessible from the World Tree portal hub when the event is active. Enemies there drop double moon pieces, and the mini-boss has no daily lockout.
If the event is running, farm there first before touching the standard zones. Our Crimson Event guide has the exact schedule and portal location.
One hidden spot that players rarely mention is the night cycle in the Sky Rift overworld. When the in-game clock hits midnight, lunar wisps spawn near the World Tree. They drop one moon piece each and die in two hits.
I set a timer for midnight and loop between the World Tree and the Moonlit Ruins. That habit alone adds four to five extra moon pieces per hour.
Tips for Efficient Farming
Group up whenever possible. A four-player party can clear the Moonlit Ruins mini-boss and the Crescent Knight packs in under three minutes. The game scales enemy health by about thirty percent per player, but the clear speed still beats solo farming because you split up and cover more ground.
Just make sure everyone tags the mini-boss.
Time your farming to the in-game night cycle. Lunar wisps only appear at midnight, and the Crescent Knights have a slightly faster respawn during night. I set a timer for every twelve minutes and switch zones to keep the spawns active.
Sitting in one spot waiting for a single respawn is the fastest way to waste time.
Do not hoard materials for a perfect reforge before you have the weapon. I see players with fifty moon pieces who still use a basic steel katana because they are afraid to spend. Forge the Moon Cut Katana first, then reforge as you farm extras.
The base weapon is already a massive upgrade over anything you have used before.
Parrying enemies in the Moonlit Ruins speeds up kills because the Crescent Knights have slow, telegraphed attacks. A clean parry stuns them for three seconds, which lets you unload your full combo. If you struggle with timing, read our How to parry in Broken Blade guide before you start the grind.
Good parry timing can cut your kill time in half.
Inventory management matters more than you think. Moon pieces, ethereal dust, and steel ingots all stack to ninety-nine, but crescent cores do not stack. Keep one inventory slot open for the core.
If your bag is full when the mini-boss dies, the core will drop on the ground and despawn after thirty seconds. I lost my first core this way and had to wait a full day.
Best Race and Build for Moon Cut Katana
Vanir is the best race for Moon Cut Katana because of the 25 percent katana damage bonus. That passive applies to every slash, every dash attack, and every critical hit. The bonus is multiplicative with other damage sources, so it scales as you improve your gear.
If you do not have Vanir, any race with a physical damage or critical rate bonus still works, but Vanir is the clear top choice.
For stat allocation, prioritize strength and critical rate. Strength raises the base damage of the katana, while critical rate helps you trigger the high burst numbers that make this weapon feel powerful. I run a 70/30 split between strength and critical rate on my main build.
That gives me consistent white damage from strength and frequent yellow crits from the rate investment.
Pair the weapon with a moon or elemental blessing that matches your reforge stat. If your reforge gave fire damage, use a fire blessing. If you got critical damage, use a moon blessing for the extra critical rate.
Matching your blessing to your weapon stat is a bigger damage gain than most players realize. A mismatched blessing costs you roughly fifteen percent of your potential damage.
For PvP, consider putting a few points into movement speed. The Moon Cut Katana has a longer dash range than the steel katana, but you still need to close gaps against ranged builds. Extra speed helps you dodge projectiles and position for parries.
PvE builds can skip speed and dump everything into strength and critical rate.
How Moon Cut Katana Compares to Other Katanas
The early-game steel katana is fine for leveling, but it falls off hard after level 30. The Moon Cut Katana outpaces it by roughly 40 percent base damage and has an elemental slot that the steel version lacks. If you are still using the starter katana at level 25, the Moon Cut Katana is a night-and-day upgrade.
The difference is immediately visible on the first hit.
The only katana that rivals it is the Dragon Slayer blade, which requires endgame raid materials. That weapon beats the Moon Cut Katana in raw damage, but the farm is significantly longer. Most players should stick with the Moon Cut Katana until they are ready for raid content.
There is no reason to delay your mid-game power spike for a weapon you will not need until level 50.
For PvP, the Moon Cut Katana has a longer dash range than the steel katana, which helps you close gaps against ranged builds. The swing speed is average, so you still need to parry or dodge to win trades. It is not an auto-win weapon, but it is one of the best all-around katanas you can get before raids.
If you face a Dragon Slayer user, you can still win by outplaying them; the gear gap is not insurmountable.
Frequently Asked Questions
Where can I get early katana?
You can get your first basic katana from the starter weapon quest in the World Tree hub. Speak to the weapon master NPC after completing the tutorial. That gives you a steel katana strong enough to carry you to level 25.
How to unlock the katanas?
Katanas are unlocked by finishing the forge tutorial quest at the World Tree blacksmith. Once you forge one iron sword, the Katana tab opens in the forge menu. You must then farm the specific materials for each katana blueprint.
How to get katana moomoo?
Moomoo is a common misspelling players use when searching for the Moon Cut Katana. The correct weapon is the Moon Cut Katana, which you craft at the forge using moon pieces, ethereal dust, steel ingots, and one crescent core.
How to get broken hero sword sailor piece?
The broken hero sword and sailor piece items belong to a different game, not Broken Blade. In Broken Blade, the closest equivalent is the Moon Cut Katana, which you forge at the World Tree blacksmith using moon pieces and a crescent core.
What race is best for katana builds?
Vanir is the best race for katana builds because it provides a 25 percent katana damage bonus. If you do not have Vanir, any race with a physical damage or critical rate bonus is a solid alternative that still works well with the Moon Cut Katana.
How does the forging system work?
The forging system lets you craft weapons by combining materials at the World Tree blacksmith. Each weapon needs a specific blueprint and materials. After forging, you can reforge a weapon to reroll its bonus stats without losing the base item or its level.
Conclusion
Getting the Moon Cut Katana in Broken Blade is a straightforward process once you know where the materials come from. Unlock the forge at the World Tree, farm moon pieces in the Moonlit Ruins or Boss Rush, collect the crescent core, and craft the weapon. After that, reforge for a strong stat bonus and pair it with a blessing that matches your roll.
I have used this exact path on two separate accounts, and both times the weapon carried me through the mid-game and into late content without any struggle. If you are serious about a katana build, the Moon Cut Katana is one of the best investments you can make in 2026. Start with the forge tutorial tonight, and you will have the blade in your hands before the weekend.
