Yamato Guide
From zero to Yamato — the complete 4-Star Katana forging route
Space Invaders, Red Orbs, Katana Pieces — every step, every material, no guesswork.
Recommended Route
Yamato is the newest endgame weapon in Broken Blade, introduced with the Reforge the Yamato update on June 12, 2026. It is a 4-Star Katana inspired by Vergil's iconic blade from Devil May Cry, and it is currently the highest-star Katana in the game. Getting it requires a massive grind: 5 billion Money, 60 million Gems, thousands of Katana Pieces, 10,000 Fire Seeds, 1,000 Red Orbs from a brand-new Space Invaders enemy type on Midgard Island, and the Space Element as a prerequisite. This guide covers the complete route from preparation to final forge, including the most efficient Red Orb farm, material farming spots, and what to expect from the Space Invaders encounter.

Quick Answer — How to Get Yamato
Before you can start the Yamato grind, make sure you have obtained the Space Element. This is a hard prerequisite — the forge will not accept your materials without it. Space Element is obtained through the new Space system tied to the Midgard Island (Dungeon Island) update.
Travel to Midgard Island (also called Dungeon Island). This is where the new Space Invaders enemy type spawns, and where you will find the Yamato forging fragments.
Defeat Space Invaders on Midgard Island to collect Red Orbs and Space Ore. You need 1,000 Red Orbs for the Yamato forge. Space Invaders are the only reliable source, so settle in for a dedicated farm session.
Collect the remaining materials: Money, Gems, Katana Pieces I-III, and Fire Seeds. These accumulate through normal gameplay — the only real bottleneck is the Red Orb farm.
With all materials in hand and the Space Element already active, visit the Forge NPC on Midgard Island to craft Yamato. The forge consumes all materials and gives you the 4-Star Katana immediately.
Complete Material Requirements
Yamato requires seven different materials plus the Space Element prerequisite. Some materials build up naturally through normal play, while Red Orbs require dedicated farming from Space Invaders. Here is the full list:

| Katana Piece II | 4,000 | Chests / Boss drops during normal play |
| Katana Piece III | 2,500 | Chests / Boss drops during normal play |
| Fire Seeds | 10,000 | Exploring islands |

Money, Gems, Katana Pieces, and Fire Seeds will accumulate over time as you progress through the game. The only material that requires a completely new dedicated farm is Red Orbs — everything else should be close to ready by the time you reach Midgard Island.
Prerequisite — Space Element
Space Element is the hard gate for forging Yamato. The Forge NPC will not process the craft unless you have this element active. Space Element was introduced alongside the Reforge the Yamato update and is tied to the Space system on Midgard Island.
To obtain Space Element, you need to interact with the Space system on Midgard Island. Defeating Space Invaders and collecting Space Ore contributes to unlocking this element. The exact unlock conditions involve the Space Shop and progression through the Space Invaders encounter.
If you do not have Space Element yet, prioritize farming Space Invaders and checking the Space Shop on Midgard Island. The shop uses Red Orbs as currency and may offer the element directly or unlock it through progression.
Do not start the material grind for Yamato until you have confirmed Space Element is unlocked. Wasting time collecting 5B Money and 60M Gems only to find the forge blocked by an unmet prerequisite is a common mistake.
Step 1 — Prepare Your Weapon for Midgard Island
Before heading to Midgard Island, make sure your current weapon setup can handle the Space Invaders. These enemies are part of the new endgame content and hit harder than standard mobs on earlier islands.
Katana users have a natural advantage here since the Yamato forge itself requires Katana Pieces — farming with a Katana lets you double-dip on material collection while clearing Space Invaders.
A well-upgraded Dragon Slayer or Moon Cut Katana is recommended for farming Space Invaders efficiently. If you are still working with lower-tier weapons, consider upgrading before committing to the Yamato grind. See the weapons guide for upgrade paths.
Bring plenty of potions and make sure your Soul Forge level is decent. Space Invaders deal consistent damage and farming 1,000 Red Orbs takes many rounds.
Step 2 — Travel to Midgard Island (Dungeon Island)
Midgard Island, also known as Dungeon Island, is the new zone introduced in the Reforge the Yamato update. It is accessible through a portal from earlier endgame zones.
Once inside, head up the stairs toward the central platform. You will find several key NPCs clustered together: the Mastery NPC, Space Shop, and Boss Quest NPC. The first circular pedestal near this group is where you find the Yamato forging fragments.
Interact with the pedestal to collect the broken Yamato fragment. This is the starting point for the forge quest — without this fragment, you cannot craft the weapon even if you have all materials.
The Space Shop on Midgard Island uses Red Orbs as currency. Check it regularly — it may offer useful items alongside the Space Element progression. Saving some Red Orbs for shop purchases before spending all 1,000 on the Yamato forge is a good strategy.
Step 3 — Farm Red Orbs from Space Invaders
Space Invaders are the new enemy type added to Midgard Island. They are the only reliable source of Red Orbs — the key bottleneck material for Yamato. You need 1,000 Red Orbs total.
Space Invaders also drop Space Ore, which is used for other Space-related crafting. Stock up on both while farming.
The most efficient farm strategy: find a spawn-dense area on Midgard Island where Space Invaders cluster and clear them in loops. Use AoE attacks to maximize kills per minute. Katana's wide swings are effective here.
Red Orb drop rates from Space Invaders are not yet fully datamined, but early reports suggest approximately 1-3 Red Orbs per kill depending on the Invader type. Plan for a multi-hour farm session to reach 1,000.
If you get tired of pure Space Invader farming, rotate between Invader clears, checking the Space Shop, and farming Fire Seeds on other islands. A varied routine keeps the grind manageable.
Step 4 — Collect Remaining Materials
While farming Red Orbs, keep an eye on your other material counts. Katana Pieces I-III drop from chests and boss kills during normal gameplay — you likely already have some saved up.
Katana Piece I is the most common and you need 6,500. If you are short, focus on farming chests in earlier islands or running easy bosses that drop weapon pieces.
Katana Piece II (4,000 needed) and Katana Piece III (2,500 needed) are rarer. Boss farming on Niflheim and Nidavellir is the most reliable source for higher-tier pieces.
Fire Seeds (10,000 needed) can be farmed on any island by breaking objects and opening chests. They accumulate naturally, but if you are short, a focused hour of Fire Seed collection on a dense island will fill the gap.
Money (5 billion) and Gems (60 million) will mostly come from natural gameplay by the time you have all other materials. If you are short on Money, boss farming is the fastest way to earn.
Step 5 — Forge Yamato at the Forge NPC
Once you have all seven materials and have confirmed the Space Element is unlocked, head to the Forge NPC on Midgard Island. The forge is located near the central platform area where you found the Yamato fragment.
Interact with the forge and select Yamato from the recipe list. The craft consumes all materials and gives you the 4-Star Katana immediately — there is no additional cost or wait time.
If the forge does not respond or the recipe does not appear, double-check your Space Element status. This is the most common reason the forge blocks the craft.
After forging, Yamato is ready to use immediately. Consider infusing it with elemental effects at the Element Forge to maximize its damage potential.
Infusion Recommendations
After crafting Yamato, infusion unlocks its full potential. While the community is still testing optimal infusion paths for the new weapon, here are the early recommendations based on similar high-star Katana builds:
Space + Fire — Thematic synergy with Yamato's Space origin. Space infusion provides consistent damage across all enemy types, while Fire adds damage-over-time. This is the recommended default for general content.
4x Fire — Maximum DPS build focused on raw damage output. Best for speed runs and endgame boss fights where every second counts.
2x Holy + 2x Fire — Balanced setup if you already have Holy infusion materials. Provides consistent damage with a burn DoT.
If you have gear that boosts specific element damage, lean into that element. Katana builds benefit most from damage multipliers that trigger on hit.
Yamato vs Other Katanas — Is It Worth the Grind?
Yamato is the first 4-Star Katana in Broken Blade, making it the highest-tier option in its weapon class. Here is how it compares to other Katana options:
Moon Cut (4-Star Katana, Nidavellir) — Moon Cut was previously the best Katana option. Yamato requires significantly more materials (5B Money vs 1B, and the new Red Orb grind) but offers higher base stats. If you already have Moon Cut, it is a strong stepping-stone weapon for farming Yamato materials.
Nameless Blade (starter Katana) — Not comparable. Nameless Blade is for early-game learning. Yamato is the endgame Katana goal.
Is Yamato worth it? If you are a Katana main and want the best possible weapon for your build, Yamato is the clear endgame target. The grind is significant, but the payoff is the highest DPS Katana currently available. If you are happy with Moon Cut and do not need maximum damage, the grind may not be worth your time.
Consider your build: Katana excels with speed and combo-based damage. If your race, element, and blessing setup already supports Katana playstyle, Yamato will dramatically improve your performance. See the best builds guide for synergy recommendations.
Common Mistakes
Starting the grind without Space Element. This is the most common blocker. Confirm Space Element is unlocked before farming a single Red Orb.
Spending Red Orbs at the Space Shop before reaching 1,000 for the forge. Red Orbs are a shared currency — if you spend them on shop items, you will need even more farming to reach the forge threshold.
Underestimating the Red Orb farm. 1,000 Red Orbs from Space Invaders is a multi-hour commitment. Do not expect to finish this in one quick session.
Using the wrong weapon for Space Invader farming. Bring your best AoE weapon. Katana's wide swings are ideal. If you are using a single-target Buster, the farm will take much longer.
Ignoring Katana Piece counts. You need 6,500/4,000/2,500 pieces. These do not accumulate as fast as you think. Check your inventory before committing to the Yamato grind and farm pieces in advance if needed.
Forgetting to collect the Yamato fragment from the pedestal on Midgard Island. Without this step, the Forge NPC cannot craft the weapon.
