Quick answer
Bottomless Buffet unlocks after the three post-game Hidden Ruins are cleared with all three Tanks. It starts at Salmonid Level 50, runs in groups of three floors, locks difficulty to Survivalist, and disables Call for Help. Floor 100 is the story target; the mode continues after it without a confirmed final floor.

| Floor groups | Progress is handled three floors at a time. |
| Starting level | The displayed Salmonid Level begins at 50. |
| Difficulty | Survivalist is forced for the run. |
| Assistance | Call for Help cannot be used. Online room play remains available. |

Preparation priorities
- Develop all three Tanks during the Hidden Ruins instead of arriving with one strong build and two neglected ones.
- Use the Level 3 Hideout facilities to improve Weapon Powers and Gadget Parts before a long attempt.
- Favor reliable survival, movement, and sustained damage over a setup that only works during a short burst.
- Plan around the lack of Call for Help. A failed solo attempt cannot be rescued through that feature from inside this mode.
- Recheck equipment between three-floor sets whenever the current setup stops keeping pace with the rising level.

Floor 100 and the true ending
Floor 100 is the meaningful finish line for the story. Reaching it opens the secret encounter; clearing that objective leads to the true ending and the Endless Search Relic Power. You do not need to keep descending after floor 100 to complete the narrative route.
Is there a maximum floor or level?
No final floor has been announced. Nintendo describes the dungeon as going deeper with no apparent end, and the mode continues after its floor-100 story target. Floor 100 is the finish line for the narrative route, not the final optional challenge.
The starting Salmonid Level is 50. Enemy levels rise as floor groups are cleared, but the game does not present that as a maximum player level or equipment cap.
