Ouwigahara, the level 65 dungeon

Ouwigahara is an endless climb. You fight floor after floor of demons, pick a card between floors, and bank tower points until your hearts run out. The points buy experience, mastery, Wen and ore in its hub, and they are the only way to pay for a V2 weapon. The game never tells you it exists: a blacksmith opens it at level 65.

Opening it once, then queueing from the menu

The first time

Reach level 65 and find Blacksmith Togane in Hidden Mist Village. His forge is on a lower level of the village, so drop down to reach it.
Pick Your other forge, then Ill find the forge(Lv 65). The quest is The Forge Above, and its only step is Ouwigahara portal opened.
Walk to the purple portal past Final Selection Plains and press T at the Ouwigahara prompt. The route from the Mistfall Harbor shrine is on the map page.

Every run after that

Open the main menu and pick the Ouwigahara Normal tile. Ranked Off sits to the left of QUEUE; turn it on and the run counts for the hub’s season leaderboard. Queueing this way, you no longer have to walk back to the portal. The other tiles on that menu are PvP; see the Zenith and ranked page.

The game's mode menu with five tiles, one of them highlighted, and a queue button under it — The main menu's mode tiles: `1v1`, `3v3`, `Ouwigahara Normal`, `2v2`, `Zenith`. Under the selected one: `Ranked Off`, `QUEUE`, `Fill Off`.

A player in a forge talking to Blacksmith Togane, a level 65 option highlighted — `Blacksmith Togane`: `Trouble is the portal past the plains. Shut for years. Go and open it.` The highlighted option is `Ill find the forge(Lv 65)`.

A player in front of a huge swirling purple portal, an enter prompt beside it — The prompt reads `Ouwigahara` over `T` `Enter`. The minimap in the top right labels `The White Terror Lair` and `…Selection Plains`.

One run, floor by floor

There is no sign of a time limit: the clock at the top counts up, next to the floor number and how many enemies are left. A Normal run gives you three hearts, shown bottom-left. Ranked gives you one.

In the hub
Stand in the inner portal. A short countdown starts and counts the players who are ready, so a party can climb together.
The portal inside the hub: Normal climb starting, 14, 1 player ready.
After every floor
A hand of cards, and solo you keep two of them within the 30-second bar. Some cards are a permanent stat bump for the run, some heal, some add points straight to your score. Reroll redeals the hand if you have a ticket.
Solo: pick 1 of 2, with 28 seconds left: Second Wind, Max Stamina +15, Tectonic Shift, Greater Trophy +375, +2 Rerolls, and a Reroll button. Below: Floor 1, 20s, Best 82, 0 caches.
Floor 10
The first boss floor. It can be a Hand Demon, the same kind as the one in Final Selection, with no drop list on its bar. Then a milestone hand, which can add a harder rule for the next floor in exchange for more points (the three cards are below).
Floor 10, 6:22, 1 left: a Hand Demon with a small bar over its head and no drop list. Three red hearts sit bottom-left.
Floor 42
A good run reaches this floor in 48:38 with 101,639 points, enough for one V2 craft. A boss spawns every ten floors, and by around floor 80 the Yetis are blowing things up.
Floor 42, 48:38, Next wave in 9. The points panel top-right reads 101,639.
When your hearts run out
You land back in the hub with a banner: floor reached, time, points, and how many caches you earned. A cache is a free chest for every ten floors, added in the V.12 patch. Die on floor 10 and the chest is waiting; a run to floor 77 earns 7 caches.
In the first week, a death sometimes dropped players outside the map instead, unable to move or type. Resetting a few times sometimes puts you back; otherwise leave. V0.18 says banked chests return after a crash or a mid-climb exit, though some players still report missing rewards. More fixes are on the controls and bugs page.
Back in the hub after dying: Floor 10 reached, 4:20, 2,651 points, Best 82, 1 cache. The open chest gave Coin three times. Above: Milestone: pick 3 of 4.

Milestone event cards

Card	Points	What the card says
No Guard	x1.3	Next floor nobody in the party can block. That floor pays 1.3x points.
Fog of War	x1.2	Next floor enemies have no outline marking them. That floor pays 1.2x points.
Marathon	x1.15	Maps change half as often: each map lasts twice as many floors before its milestone hand. Every floor pays 1.15x points.

Skip is the fourth choice in a milestone hand. No Guard can get you infinitely comboed.

Four large cards on screen, three of them offering a points multiplier for a harder floor — A milestone hand on `Floor 10` at `7:31`: `Skip` (`No event this floor.`), `No Guard, x1.3 points`, `Fog of War, x1.2 points`, `Marathon, x1.15 points`.

Scoring more points

Depth is where the points are. Of the runs above, one that stopped on floor 42 banked 101,639, and one that reached floor 77 banked 442,794. Surviving longer is the surest way to a bigger total.

Take the big multipliers when you can survive them. Besides the three cards in the table above, milestone hands have also offered Iron Discipline (x2.4), Cursed Coin (x2), Gold Rush (x2), Thin Air (x1.25), Heavy Air (x1.25), Grounded (x1.2), Lights Out (x1.2), Elite Guard (x1.15). Blood Moon reportedly halves health for 1.5x points, and one player says Fair Fight is mostly for quicker clears rather than points. Trophy cards in a milestone hand add points outright, and the higher the tier, the more they are worth.

Solo or duo, not Ranked. A Ranked run gives you one heart instead of three and reportedly pays fewer points. Solo reportedly pays more per player, but one duo reports 400,000 or more in about an hour and twenty minutes.

One run, one total. Creators report that nothing carries over to the next queue, so a big purchase has to come from a single climb.

A milestone hand with two trophy cards that add points — `Milestone: pick 3 of 4`: `Grand Trophy +750` and `Greater Trophy +375`, `Points added straight to your score. The higher the tier, the more kills it is worth.` Beside them `Second Wind`, `Damage +1` and `Cheap Seats`.

Spend it before you queue again

After a run, the counter on your screen equals that run’s total. The points do not stay when you queue again, so plan the whole basket from one run.

Points on your counter after the run

Or start from an example run:

A V2 craft alone takes 90,000, and points reportedly do not carry over to the next run, so that has to come out of a single climb.

A blue crystal stall with twelve item icons priced at 3,000 each, and a run summary banner above — `Tower Crystal`: `Trade your tower points for mastery in any weapon or power you own.` Twelve icons at `3,000` each. The banner above: `Floor 77 reached`, `2:18:53`, `442,794 points`, `New best`, `7 caches`.

A stall in the hub with three shelf items and a dialog box — `Changer Zeni`: `I trade tower points for Wen and refinement ore. Pick what you want from the shelf.` Shelf: `2,500` (`1,000 Wen`), `1,500`, `30,000`. The counter reads `2,651`.

Since the V.12 patch, 2,500 points buy 1,000 Wen instead of the old 500. Two ores on Changer Zeni’s shelf carry no name, only an icon. The hub’s APOTHECARY is Alchemist Meku again: his three elixirs cost two Demon Horns each on top of the Wen, as at the harbour, while the regen potions there are Wen only. Every price is on the elixirs page.

The chest, and the Nightfall drops

The Ouwigahara Chest in the courtyard opens for 30,000 points. What comes out is mixed: accessories such as the Red Oni Mask, potions, coin pouches, and the Metal Scraps and Silk Thread a V2 recipe eats. Now and then a Nightfall Forged Ingot, one of the three materials behind every Nightfall tier and armour piece (see Nightfall and Firstlight). Two hats that block the sun for demons, the Straw Fringe Hat and the Flame Amigasa, also come from this chest; see the sun immunity hat page.

Nightfall materials drop from about 5% of these chests, and normal world chests drop them less often. The Archives card for the Firstlight Forged Ingot follows the same pattern: 5% from the Ouwigahara Chest, 2% from a World Events Chest. At 30,000 points a chest is expensive for what it usually gives.

A player next to a large black chest in a stone courtyard, with an open prompt — `Ouwigahara Chest`, `Open (30,000 points)`.

A column of item pop-ups beside a player who has just opened a chest — One chest's pop-ups: `Azure Drape Scarf` (`NEW!`), `Coin Pouch`, `Eye Sash`, `Health Regen Potion`, `Metal Scraps x19`, `Mimic Necklace`, `Nichirin Lantern` (`NEW!`), `Red Oni Mask`, `Silk Thread x20`.

An item lying on the ground next to a player, with a claim prompt — On the ground: `Nightfall Forged Ingot`, `Claim`.

The points buy V2 weapons

The Nichirin Forge stall in the hub turns a base weapon into its V2 for 90,000 points plus 500 Metal Scraps, 10 Mythic Refinement Ore and 300 Silk Thread. The points come off the run’s total: a counter at 101,639 drops to 11,639 after one craft. You do not earn 90,000 once to unlock V2; it is the price of each craft. Every weapon line and its tiers are on the weapons page, and the Insect line is worked through on Insect Breathing.

Tips for long runs

Stats first, points later. Take the cards that make you tougher on early floors and the point cards once the numbers get big. The opposite order can also work on very long runs.
Skip attack speed. You do not need it if your damage comes from your ultimate move.
Bring moves, not just M1. Have all four skills you can get before the ultimate; you do not need the ultimate itself.
Duo spawns more. In solo some waves hold six enemies but only four spawn at a time; duo is even better.
The top has a title. Reaching the top of the tower is what Heaven’s Doorstep asks for, and players say it takes a hidden title from an earlier deep run first. The route and the other six tower titles are on the titles page.

90,000 points on a phone, and missing caches

There is no fixed floor that guarantees 90,000 points. Card choices and the run change the result; reportedly the score must come from one climb. Check your points before banking on a reforge.

Some mobile players report late-floor crashes or a crash as the run ends. Lower graphics and effect settings may make the game easier to run, but they do not guarantee a stable climb. V0.18 says banked chests return after a crash or exit; players still report missing rewards, and there is no confirmed manual recovery procedure here.

Use the chest guide to distinguish caches from points. Record the floor, score and exit result if a reward is missing, rather than treating the next climb as a continuation of this one.
