Slayers 2 Dungeon Guide: Ouwigahara
The Slayers 2 dungeon is Ouwigahara, a floor-by-floor climb with its own lobby, shops and Ranked leaderboard. It is the main endgame loop: V2 weapon recipes, mastery XP, Wen exchange and the leaderboard season all live here. Everything below is community-documented (All Things How and Nerds Chalk routes, cross-checked October 2026).

How to unlock the dungeon
- Reach level 65 on the character you plan to run. Lower-level characters can see the quest line but cannot pick it up.
- Go to Hidden Mist Village and talk to Blacksmith Togane at the forge. Pick "I'll find the forge (Lv 65)" — his second forge, per the quest dialogue.
- The quest points you toward Mistfall Harbor Shrine and the Forgotten Ruins. Cross the long stone bridge out past the Rengoku marker.
- Stay on the road through the torii gates — the path is longer than it looks and only shows fully once you drop below the mist line, so do not double back.
- At the end of the road, walk into the swirling purple portal to register it. It takes you to the Ouwigahara lobby.
- Open the HUB from the main menu — if Ouwigahara Normal is listed next to 1v1, 2v2, 3v3 and Zenith, the unlock worked. From now on you never walk the route again; it queues from the menu.
Bring Wall Climb for the route; a mount helps but is optional.
What to bring
- Level 65 — a real entry point, not a number to overshoot.
- One or two moves — any breathing style or blood demon art works, but unlock one or two of its moves first. M1 attacks and a starter katana are not enough.
- A weapon you have inspected — its Damage Factor and Block Points stack with every card you pick up inside.
- Defence before raw damage — enemy damage scales faster than enemy health, so HP and damage reduction from your armour keep a run alive past the early floors.
Style picks from the guides: Serpent, Insect, Sound or Thunder for slayers; Blood Sickles or Shockwave builds for demons. Clan picks: Kamado for demons, Rengoku for slayers. Gear-wise, a Duelist or Tank set with the Serpent Katana or Mythic Damascus Sickles is the documented start — still on starter gear? Farm Zuko first: his Cutlass is a reported 20% drop and carries the Quick Draw skill.
The Ouwigahara lobby
Everything sits a few steps from the queue portal, so stock up here instead of in the open world:
| Station | What it does |
|---|---|
| Apothecary (Alchemist Meku) | Stamina Regen Potion for 140 Wen + 2 Demon Horns; Health Regen Potion for 600 Wen + 6 Demon Horns |
| Nichirin Forge (Togane) | Tier 2 (V2) weapon recipes and reforging |
| Tower Crystal (EXP AREA) | Mastery levels and XP for dungeon points |
| Changer Zeni (WEN AREA) | Trades points for Wen and Mythic Refinement Ore (reported 100 Wen per 25 points) |
| Ouwigahara Chest | Random rewards for points |
| Leaderboard | Ranked Normal scores and the season timer |
| Queue portal | The purple portal in the middle starts a run |
Demon Horns for the potions drop from the demons in the cave beneath the bear area.
How a run works
Pick Ouwigahara Normal, choose solo or group, and switch Ranked on or off before the countdown ends. A 20-second countdown takes you in, and a second 30-second countdown runs on floor 1 before the first wave. The rules that matter:
- Normal grants 3 lives, Ranked grants 1 — one death ends a Ranked attempt.
- Every floor ends with a card choice (below).
- Every tenth floor is a milestone with a boss; free chests have dropped every 10 floors since the V0.195 patch.
- Death ends the run and returns you to the lobby — the end screen shows your floor and time.
- The leaderboard ranks total points, not deepest floor — a run built on multipliers can beat a deeper run on stat cards alone.
- Points do not carry over — spend them before you queue again.
Best cards in the dungeon
Each floor offers two kinds of card: stat cards that change your character, and modifier cards that change the dungeon in return for a point multiplier. A multiplier that lasts the rest of the run is worth more the earlier you take it. Two priority picks the guides agree on: take Lucky Draw (a Legendary card that improves your later draws) as early as it shows up, and take Vampiric (heals you on every kill) whenever it appears.
| Card | Effect | Points |
|---|---|---|
| Gold Rush | Point modifier — community notes add that you keep your weapons | x2 |
| Cursed Coin | Point modifier | x2 |
| Blood Moon | Enemies have half their health but hit harder | x1.5 |
| No Guard | Harsh defensive modifier | x1.3 |
| Double Time | Speed modifier | x1.3 |
| Boss Hunt | Bosses spawn on each floor | x1.25 |
| Thin Air | Floor modifier | x1.25 |
| Fair Fight | Changes enemy spawns — nobody deals or takes critical hits next floor | x1.2 |
| Fog of War | Less visibility | x1.2 |
| Thick Skin | Tougher enemies | x1.2 |
| Ascension | One extra elite enemy per floor | +1.2 |
What points buy — and the real prize
Points convert at Changer Zeni (reported 100 Wen per 25 points) or exchange for Mythic Refinement Ore and random chest pulls. But the reason endgame players run Ouwigahara is the Nichirin Forge: Tier 2 (V2) weapon recipes — the documented Thunder V2 bill is 10 Mythic Refinement Ore, 500 Metal Scraps, ~300 Silk Thread, 90,000 Wen and your original katana — plus a reported 90,000-point requirement for the top Tier 2 weapons. Higher-tier weapon progression reportedly needs 500 scrap, 500 silk, 10 mythic refinements and that 90,000-point run, so collect materials throughout the campaign, not after.
Preparation checklist
- Max your breathing forms — the tier list tells you which style fits your clan.
- An S-tier clan (Kamado/Rengoku) makes solo runs dramatically easier — see the reroll guide if you're still on a Common.
- Stock Demon Horns before you queue — the lobby potions take them as well as Wen.
- Damage cards early, point cards later — survival first, then multiplier scaling.
- Play with friends when an activity is hard to clear alone; dungeon matchmaking reportedly exists for Ouwigahara.
Unlock route, lobby prices, card list and point economy are community-reported (guides cross-checked October 2026, post-V0.195) and can change with updates.
