  Deep Dungeon Rules
─────────────────────────────────
・All 50 floors, and the deeper you descend, the harder it gets.
You can probably push through to around Floor 20,
but past that, whether it's even clearable is anyone's guess.
A full party is strongly recommended.
Even with a full party, Floor 30 may be brutal.

・The dungeon's size differs on each floor.
Floors 1–5: Small / Floors 6–10: Medium / Floors 11–50: Large

The dungeon buyer of the first party to clear each floor
is recognized as that floor's "Floor Master."

And the first party to clear the deepest floor
is recognized as the "Hero Party."
