Ouwigahara is the wall that separates mid-game Slayers 2 from the endgame. It is an endless wave mode built around points rather than loot, and those points are the only currency that buys V2 weapons, Mythic Refinement Ore, and mastery boosts. The portal will not accept you until a blacksmith in Hidden Mist Village sends you looking for his second forge, and that conversation is hard-gated behind character level.
Quick answer: Reach Level 65, speak to Blacksmith Togane in Hidden Mist Village, choose “Your other forge,” then take the purple portal past Mistfall Harbor to register Ouwigahara to your hub menu.
What you need before the Ouwigahara portal will work
The level requirement is absolute. Everything else on the list is about surviving long enough to bank points, because a run that dies on Floor 12 is worth almost nothing.
- Level 65 — below this, the quest dialogue will not advance.
- At least one or two unlocked Breathing or Blood Demon Art moves. M1 attacks alone stall out fast.
- Wall Climb, which covers the ledges on the approach route.
- A full stack of healing potions and elixirs, bought before the run book starts the climb.
- A horse or mount, optional but a large time saver on the overland route.
Unlock the quest with Blacksmith Togane in Hidden Mist Village
Before leaving, open his crafting board and material exchange. The board lists the full Firstlight and Nightfall weapon and armor requirements, and the exchange trades between Forged Ingot, Star Ore, Weaver’s Silk, Reinforced Plating and Weaver’s Cloth.
The route to the Ouwigahara portal past Mistfall Harbor
The quest marker points west, but the destination is simple enough to run blind. Everything past this point sits on one long road of wooden bridges.
How to confirm the dungeon is unlocked
Back out to the main menu. Ouwigahara Normal sits beside the 1v1, 2v2, 3v3 and Zenith modes, and the padlock icon is gone once the portal has registered to your hub. From then on you queue straight from the menu instead of riding the bridges again. A second confirmation waits inside: find Togane on Floor 1 and open his menu, and the Nichirin Forge list should be selectable rather than locked. The Slayers 2 experience page on Roblox is the fastest way back in if you need to rejoin a server.
How Ouwigahara runs pay out Dungeon Points
Ouwigahara is a climb through waves. You clear mobs, pick a buff card between floors, and can stack modifiers that raise difficulty in exchange for point multipliers. Up to five players can queue together. Orbs drop from defeated enemies for temporary boosts, and timed events — time stop, double health, blocked healing, blurred vision — cut in and out during the climb.
Card choice decides the score more than floor depth does. Permanent multipliers that apply to every floor compound, while a card that buffs only the next floor is close to worthless.
- Lucky Draw — improves the rarity of every later card draw. Take it on sight in the early floors.
- Ascension — 1.2x points and one extra elite per floor, best on high-damage builds.
- Blood Moon — 1.5x points, with enemies hitting harder but carrying less HP.
- Vampiric — life-steal on abilities, which preserves your potion stock.
- Stat cards, in order: Damage, Max HP, Cooldown Reduction, Damage Reduction, Block Points.
Skip Grounded, which disables your dash and double jump. Attack Speed and Movement Speed are the weakest picks, and cards that only disable debuffs generally waste the slot.
Floor 10 closes with the Hand Demon and a milestone card choice, after which the waves get noticeably harder. Past Wave 60 the enemy stat jump makes M1 combos unsafe, so switch to ability cycling and hit-and-run movement. Clearing around Floors 60 to 70 usually pushes you past 90,000 points, but speed matters more than depth — a strong run through Floor 50 can clear 150,000 points in roughly 48 minutes. Finishing Floor 51 unlocks the Ouwigahara Chest.
Dungeon Points do not carry between sessions. Spend the entire balance in the lobby shop before you leave, or it resets to zero.
Where Dungeon Points go
| Purchase | Cost | Best for |
|---|---|---|
| Training Boosters | Varies | Sword, BDA and Breathing mastery |
| Ouwigahara Chest | 30,000 | Legendary accessories |
| Mythic Refinement Ore | 30,000 each | V2 crafting material |
| V2 weapon craft | 90,000 | Endgame damage |
Chest pulls can return the Todoroki Koshimaki, Red Oni Mask, Nichirin Lantern or Silver Fang Mask. Each pull is a third of a V2 weapon, so decide before the shop screen whether a run is funding the forge or the accessory slot. If you are still leveling mastery, boosters are the better spend, since a maxed Breathing style or Blood Demon Art unlocks your Ultimate and makes every later run faster.
V2 weapon costs at the Nichirin Forge
V2 weapons never drop, trade, or sell. Every recipe shares one core cost, then consumes the specific V1 katana it upgrades plus materials tied to its dungeon.
| Requirement | Amount | Where it comes from |
|---|---|---|
| Dungeon Points | 90,000 | Ouwigahara runs |
| Metal Scraps | 500 | Chests, Ginzo |
| Silk Thread | 300–400 | Chests, Ginzo |
| Mythic Refinement Ore | 10 | Points or Mythic salvage |
| Base weapon | 1 | The V1 katana being upgraded |
Points are the slowest line to rebuild, so treat 90,000 as the real gate. Scraps and thread accumulate from chests on their own, and Merchant Ginzo at Mistfall Harbor sells both outright if you are short at the end. Buying all ten ores with points would cost 300,000 — far better to complete Denzo’s quest for salvage access and break down duplicate Mythic gear, or sell surplus mythics to Ginzo, who converts them into ore.
Base katanas and the bosses that drop them
Every recipe consumes a particular V1 weapon: the Thunder Katana upgrades into the Thundercloud Katana, while the Flame Katana turns into the Volcanic Katana. Each drop has only about a 5 percent chance, making the farming phase longer than the forging itself.
| Katana | Boss | Where |
|---|---|---|
| Wind | Sanemi | North of Beginner Village |
| Insect | Shinora | North past Sanemi, toward Mistfall Harbor |
| Flame | Rengu | Forgotten Ruins, across the bridge |
| Serpent | Obari | Bamboo Grove, west of Beginner Village |
| Thunder | Zentaro | Pit near Obari in the Wilderness |
| Water | Giyen | East of Hidden Mist Village Shrine |
| Sound | Tengai | Snowy town near Frost Veil Shrine |
| Axe and Mace | Stone Trainee | Stone Sanctuary, west of Hidden Mist Village |
Pick your main before farming. Crafting destroys the base weapon, and one finished V2 beats three half-built ones.
Placing the craft
When the run ends, return to the hub and walk into the Weapons Area, where Togane stands beside the Nichirin Forge. His list covers Damascus weapons as the intermediate tier, the Firstlight and Nightfall weapon and armor sets, and elemental katanas including the Volcanic, Tidal, Thundercloud, Tornadic and Butterfly. Dungeon-exclusive gear such as the Seismic Axe and Mace with +4.4 Additional Damage is built here too. Select the recipe matching the katana in your inventory and confirm; the forge takes the base weapon, points, scraps, thread, ore and Yen in one transaction.
Recipes stay visible even when you do not own the matching schematic. Seeing an entry is not the same as being able to craft it.
Firstlight and Nightfall schematic locations
Schematics are tangible items placed throughout the world. Studying one adds it to the schematics tab in your inventory. Reaching them usually involves swimming, climbing, activating a lever or solving a puzzle.
| Schematic | Region | Where it sits |
|---|---|---|
| Firstlight Insect Katana | Mistfall Harbor | Submerged cave under the river |
| Nightfall Katana | Mistfall Harbor | Pedestal in the flooded sewer tunnel |
| Nightfall Claws | Icy cliffs near the Yeti | Deep underwater cavern |
| Firstlight Lantern | Bamboo Grove | Upper floor, behind a floor plate puzzle |
| Nightfall Axe and Mace | Bamboo Grove | Pagoda rooftop, via the outer wall lever |
| Firstlight Katana | Icevell Valley | Hidden ice cave system |
| Nightfall Scythe | Icevell Valley | Side path past the Firstlight Katana |
| Firstlight Spear | Icevell Valley | Icy pedestal at the end of a snow tunnel |
| Sound Cleavers | Icevell Valley | Cavern held by Duelist Hibiki |
Icevell Valley
Four of the nine sit here, and the caves are pitch black. Fast travel in, light your Emberheart Lantern at a campfire, then drop into the water hole behind the statue to reach the ice caves. The Firstlight Katana comes first, the Nightfall Scythe branches off a side path, and the Firstlight Spear waits at the end of a snowy tunnel.
Duelist Hibiki and the Sound Cleavers
The Sound Cleavers schematic is handed over by an NPC rather than picked off a pedestal. Duelist Hibiki sits in a snowy cavern reached by parkouring across floating platforms, and he fights back. Bring a second player if your build is unfinished.
Bamboo Grove and Mistfall Harbor
The two Bamboo Grove schematics occupy one pagoda, although each requires a separate route. On the upper floor, complete the floor-tile memory puzzle to obtain the Firstlight Lantern. Then reach the upper ledge and operate the lever on the outside wall, opening the roof route to the Nightfall Axe and Mace. Both harbor schematics require swimming: the Firstlight Insect Katana is in an underwater cavern reached through the river, while the Nightfall Katana lies in a flooded chamber accessed through the drainage sewer pipe beneath the harbor. Farther out, beyond a hidden underwater passage descending the icy cliff wall, you can find the Nightfall Claws.
Damage gear that raises your point total
Damage determines the point total, so adding Additional Damage before climbing is more efficient than running shallow floors repeatedly. A rare clan roll is unnecessary for any of this.
| Item | Effect | Source |
|---|---|---|
| Stone Haori | +2 damage, 1.02x, +100 HP, +80 stamina | Stone Hashira, Stone Sanctuary |
| Demonic Lantern | +2 damage, 1.01x, +0.8 Illumination | Chests |
| Flame Scarf | 1.06x damage factor | Chests |
| Flame Haori Style 2 | +1 damage, 1.01x | Rengu (3%) |
| Bamboo Muzzle | Extra damage | Nezura (3%) |
From spawn, travel past Mistfall Harbor to find Nezura. For the Stone Hashira, use the narrow ledge beside the Stone Sanctuary; it is the most difficult farm here, and that position lets you reset and heal against the wall. Low-odds masks, including the Bamboo Muzzle and the roughly 2 percent Sabito mask, are poor targets because legendary dungeon masks such as Demonic Horns II are stronger.
Titles add to accessory bonuses. Bonebreaker contributes +1 Additional Damage, Monster Hunter supplies a 1.01x factor, and Hard Hitter contributes +0.75; Reaper and Annihilator belong to that group as well. Combining them can reach about +12.43 Additional Damage and a 1.34x factor without a rare clan, enough to handle deep floors. At the Hidden Mist Village forge, Refiner Hagane uses Wen and Refinement Ores to raise a weapon toward Level 10, but the success rate falls sharply near the top—the 8 to 9 attempt is about 5.5 percent. Use Refinement Guards for these attempts, since failing without one may downgrade the weapon instead of merely consuming materials. In the Skill Tree, put Additional Damage into M1 output first, then spend points on Max Health, Stamina Regen and Block Points.
How to confirm the V2 craft registered
Three checks cover it. Open the schematics tab and look for the studied blueprint by name. On Ouwigahara Floor 1, open Togane’s menu and confirm the Damascus, Firstlight and elemental katana lists are selectable rather than greyed out. After the craft, check your inventory — the V2 weapon should have replaced the base katana, with its stat line showing in the Archives.
The clearest signal is back in the main world. Return to the Blacksmith, open his menu, and look for the matching V3 recipe: a successful V2 craft unlocks it. That next tier asks for 1,000,000 Cash, 1,000 Silk Thread, 1,000 Metal Scraps, the V2 weapon itself, and its own hidden schematic. Since Firstlight and Nightfall items pull from the same ore and point pool, finish one weapon completely before committing the next 30,000 points anywhere else.
