Bottomless Buffet: The Endless Dungeon, Floor by Floor
Unlock requirements, the rules that change below ground, the floor-100 secret boss, and the builds that survive the descent.

What the Bottomless Buffet Is
The Bottomless Buffet (JP: 無限食堂) is the post-game endless dungeon under the Great Salmon Mess Hall. Floors are served in sets of three, the Salmonid Level keeps climbing, and floor 100 hides the game's secret boss and its one-of-a-kind rewards. It is the closest thing Raiders has to an endgame ladder. One update on the word endless: on 2026-08-20 a Japanese streamer cleared floor 1000, the first documented clear, and viewers of that stream report the descent stops there. We have not marked that confirmed, and our Does the Buffet End page has the evidence, what the clear pays, and where the guide sites disagree.
Nintendo has never named the mode publicly, but the developers describe it in Ask the Developer Vol. 22: once the story reaches a certain point, "you discover a dungeon where you can keep going deeper and deeper, with no apparent end in sight", built, per director Yoshihiko Ito, to test both near-limit gear and raw technique.
How to Unlock It
Two gates, both required:
- Beat the Salmonarch (JP: サルモン王) in the Throne Room at the bottom of the Great Salmon Mess Hall, the story's final boss.
- Clear all three Hidden Ruins with all three tanks: Speed, Power and Tactical. Each clear awards a relic; the full set of nine completes a special relic that opens the Buffet.
- The entrance then appears directly below the Throne Room.
The three Hidden Ruins are Fischflak (Salmonid Lv. 42) on Atke Island, Smoksam (44) on Kinp Island, and Myunyere (46) on Suma Island, or in Japanese シャカ=ハラーカ on ケシャ島, サマーカ=サーマン on モーサン島, and チャワチャワ=ヤカ on トラウ島. We previously declined to pair these names for lack of a source; the island rosters settled it. Each ruin sits on a salmon-pun island in both languages: salmon flakes (鮭フレーク) → Fischflak, smoked salmon → Smoksam, and masu trout (トラウ島/Suma = masu) → Myunyere. Full reasoning is in our All Dungeons guide.
House Rules Below Ground
| Rule | What it means |
|---|---|
| Floors come in threes | You run three floors per serving; the reward chest comes after each set. |
| Salmonid Level starts at 50 | And rises every three floors. No source has published the exact step size, so judge difficulty by how deep you are, not by the label. |
| Locked to Survivalist | Whatever difficulty you normally play, the Buffet forces the hardest setting. |
| No Help calls | The Help feature is disabled. Friend and password rooms still work, so you can bring a party; you just cannot summon rescue mid-run. |
| Quotas grow with depth | The Power Egg requirement climbs as you descend: Japanese databases record the first-floor quota jumping from 2,100 to 2,400 at floor 91. |
| Deep floors open scripted | From floor 91 the opening spawns are fixed (floor 99 is widely called the hardest serving), then reinforcements go random. |
Floor 100: Lord Saltimatum
Floor 100 is a boss arena that Japanese databases list as its own dungeon, 無限食堂黄金の間, "the Golden Chamber". Correction, August 23: this page used to say no English name had surfaced. One has. Inkipedia calls it the Gold Club, and we are taking that pairing because it closes on the boss rather than on the sound of the words: their Gold Club article names Lord Saltimatum as the enemy first introduced there, and their locations list places it between Bottomless Buffet floors 1-99 and floors 101-1000. Inside waits Lord Saltimatum (JP: シオヅケノオオミカミ). Expect a long fight: Japanese clears in gear that handled floor 99 still report roughly 10 minutes.
Our Japanese sources describe three phases of tornadoes, charge beams and projectiles, while Inkipedia's walkthrough for the same fight is laid out in five; that page is marked as under construction, so we are showing the disagreement rather than picking a number. between phases you splat Salmonids for Power Eggs and cash them in with Drill Attacks. Two practical notes from the sources: fight close (the beam is described as undodgeable at range), and keep an inked escape route. The freeze build that carries this fight is detailed in our status-effects guide.
| Reward | JP name | Type | What it does |
|---|---|---|---|
| Legendary Loot | 伝説のオタカラ | Relic | Grants Endless Search (終わりなき探求): undiscovered Gadget Parts become easier to find, and it equips in its own extra slot, on top of your normal Relic Powers. |
| Golden Forever | キンピカ FOREVER | Outfit | Cosmetic outfit: the visible proof of a floor-100 clear. |
| Salty Islands | 塩を生む島 | Briny Scroll | A lore file on where the salt comes from (the JP edition calls the collectible type an Adventure File). |
Japanese sites often call the post-Saltimatum cutscene the true ending (真エンディング); English coverage frames it as a secret-boss finale instead. The scene exists either way; only the label is disputed, so read "true ending" as community shorthand, not an official term.
What Actually Drops Down There
Every three floors the chest pays out relics, weapons and Gadget Parts; the relic pool (about 44 known rewards) is random, so completing the Relic Collection means repeat servings. Kill drops are the quieter story: Japanese databases confirm the drop tables are the normal ones. The edge is that enemy level runs far above any regular dungeon, so high-rarity rolls come more often. The Buffet's farming value is its depth, not a special loot table.
Where it fits your routine: Japanese farming guides rank the Buffet top for ★5 and Primo weapons and for Spirhalite Crystals (dense Boss and Seasoned Salmonid spawns), with the community loop being floors 97–99, about three minutes a serving in practiced runs (community-reported, unverified). Gear up on the Awlmun Den loop first; the Buffet is where you go once that stops improving you.
Builds That Survive the Descent
The consensus is the freeze meta from our status-effects guide, tuned for one-hit classes: the Japanese showcase runs Tarp Brella (シートシェルターブルー) with Ice Breaker, Meteor Mitt and Blast Boot rolled for Freeze, and Splatellites for egg collection. Rapid-fire weapons waste the freeze multiplier, though Game8's own 97–99 clear uses a Primo Lifeguard Splattershot Jr. with Freeze ★3, so the rule bends when your rolls are good.
Three force multipliers recur across sources: the Showstopper Power relic power (+12% ult gauge, and banked right that is one Showstopper per floor), Big Man as the partner pick (invulnerable ult; swap him if damage falls off in deep servings), and artillery-first targeting: Smokers, Flyfish, Stingers and Big Shots die before anything else is allowed to stack.
Past floor 100 the Buffet keeps generating floors, stages go random, and the game records a high score per build. The verified community ceiling has moved fast: the deepest run documented on video is floor 802 (2026-08-06 sweep), freeze builds are still core at that depth; they shift toward proc-rate stacking and one-shot chargers rather than fading, and no licensed outlet has covered anything past 100. Our deep floors page tracks the records and how the builds change, with the evidence behind each claim.

Numbers and Japanese names cross-checked against Game8 (EN and JP) and GameWith's 無限食堂 pages; where those sources disagree, namely the "true ending" label, partner choice and deep-floor meta, the dispute is stated in the text.
