Slayers 2 Forge unlock requirements
Before starting the V2 weapon progression, make sure you have reached Level 65. This is the main level gate for accessing the Forge progression.
You should also have enough time and resources for Dungeon farming. The exact material requirements depend on the weapon you want to craft, but the progression can involve:
| Requirement | Purpose |
|---|---|
| Level 65 | Unlocks the Forge progression |
| Mythic items | Used to obtain Mythic Refinement Ore |
| 10 Mythic Refinement Ore | Required for certain V2 crafts |
| 500 Metal Scrap | Weapon crafting material |
| 300 Silk Thread | Weapon crafting material |
| 90,000 Yen | Crafting cost for the relevant recipe |
| Ouwigahara Points | Required by certain upgraded weapons |
| Weapon schematic | Unlocks the corresponding craft |
| Prerequisite weapon | Required for certain V2 weapons |
Do not sell or discard important Mythic items or prerequisite weapons before checking the Forge recipe. Some upgraded weapons build directly from weapons you may already own.
How to unlock the Forge and start V2 progression in Slayers 2
A – Requirements and starting quest
Step 1: Reach Level 65.
You cannot properly begin the Forge progression until your character reaches the required level. If you’re below Level 65, focus on leveling before worrying about V2 crafting.
Step 2: Travel toward Mist Village and locate Blacksmith Togane.
Blacksmith Togane is located on the upper cliffs/layer near Mist Village. Look around the elevated area rather than searching through the main village streets.

Step 3: Talk to Blacksmith Togane.
Interact with Togane to begin the Forge-related quest. Follow his dialogue and objectives to unlock access to the main Forge system.
Step 4: Learn the Forge requirements.
Once the Forge becomes available, check the weapon recipes before starting your farming. This is important because different weapons can require different prerequisite weapons, points and materials.
B – Completing the dungeon
Step 5: Enter the Ouwigahara Dungeon.
The Dungeon becomes one of your main destinations for V2 progression. Before entering, stock up on healing items if necessary, since longer runs can become considerably more demanding.
Step 6: Choose useful Dungeon modifiers.
When selecting cards, prioritize effects that improve your combat performance. Damage, attack speed, cooldown reduction, damage reduction and Vampiric-style sustain are useful choices for a farming-focused build.

Lucky Draw can also be useful when it appears.
Avoid modifiers that unnecessarily restrict movement or defensive options, particularly if you’re still learning the Dungeon.
Step 7: Clear the Dungeon waves and build your points.
Continue defeating enemies and progressing through the floors. Bosses appear at regular intervals, including the documented boss encounters on every 10th floor.
Your goal is to accumulate enough points while surviving long enough to make each run worthwhile.

Step 8: Use the Dungeon Forge and collect your rewards.
When your run ends, you are taken to the end area. This is where you can access the Dungeon Forge and collect your available rewards.
The Dungeon can also provide endgame equipment, including rewards associated with the Duelist Set.
C – Collecting materials and required weapon for Forge
Step 9: Farm Mythic Refinement Ore.
For the stated crafting requirement, you need 10 Mythic Refinement Ore.
These can be obtained by exchanging unused Mythic items with the relevant merchant near the Windy Peak/Dungeon area. This gives duplicate or unwanted Mythic items another purpose during your V2 grind.

Step 10: Farm Metal Scrap and Silk Thread.
You need 500 Metal Scrap and 300 Silk Thread for the relevant V2 crafting requirements.
Open-world bosses are a useful source for these materials. You can also purchase materials from the merchant, but buying large quantities can be expensive, making boss farming a better option when you want to conserve Yen.

Step 11: Farm the required Yen.
The crafting process can require 90,000 Yen, so make sure you have enough currency before returning to the Forge.
Dungeon runs are also useful for building up your Yen supply while you’re farming other resources.
Step 12: Find the schematic for your chosen weapon.
Having the materials isn’t necessarily enough. You also need the appropriate schematic for the weapon you’re trying to craft.
Schematics can be found around the map, so explore areas connected to the Forge and Dungeon progression and complete any relevant objectives you encounter.
Step 13: Get the prerequisite weapon.
Some V2 weapons are upgrades of existing weapons.
For example, the Volcanic Katana requires the Flame Katana as its prerequisite. Other upgraded weapons similarly build from specific existing weapons.

Check the recipe for your desired weapon before farming so you know exactly which weapon you need to keep.
D – Using the forge and crafting
Step 14: Return to the Nichirin Forge.
Once you’ve gathered the required materials, schematic and prerequisite weapon, return to the Forge in your lobby and enter the Weapons Area – Nichirin Forge.

Step 15: Select your V2 weapon and confirm the recipe.
Check that you have every required item, including the correct weapon, materials, points and currency.
If something is missing, the Forge should show you what still needs to be collected.
Step 16: Craft the V2 weapon.
With all requirements satisfied, craft the weapon. Your upgraded weapon is then ready to equip and use as part of your endgame build.

What you can craft at Forge in Slayers 2
The Forge is not limited to a single weapon. It is the central crafting point for the higher-tier weapon progression, including upgraded weapons associated with different Slayer styles.
| Weapon | Prerequisite / requirement | Notable benefit |
|---|---|---|
| Volcanic Katana | Flame Katana + Ouwigahara progression | Increased sword damage and Flame-related bonus |
| Butterfly Katana | Insect Katana + Ouwigahara progression | Increased sword damage and Insect-related bonus |
| Waterfall Katana | Giyu’s Water Katana + Ouwigahara progression | Increased sword damage and upgraded effects |
| Firstlight weapons | Relevant schematic + Forge materials | Endgame weapon progression |
| Nightfall weapons | Relevant schematic + Forge materials | Higher-end weapon progression |
The Volcanic Katana is particularly relevant if you’re using Flame Breathing. Current item information lists it with +3 Sword Damage and a 5% bonus to the matching Breathing damage, making it a natural upgrade target for Flame users.
The exact available recipes and requirements can change as Project Slayers 2 receives updates, so always check the live Forge interface before committing your materials.

Completing V2 weapons progression
The complete V2 progression is straightforward once you know the order: Level 65 → Blacksmith Togane → unlock the Forge → Ouwigahara Dungeon → farm points and materials → find your schematic → obtain the prerequisite weapon → return to the Nichirin Forge → craft your V2 weapon.
The most important thing is to check your chosen weapon’s recipe before farming. That lets you know which prerequisite weapon, schematic, materials and Ouwigahara requirements you actually need, rather than grinding resources blindly.
