The 6 arenas of Blood Dungeon
Every run moves through the same 6 arenas in the same order. We have not played far enough to map out what each one looks like — what we can show is how far people actually get, read straight from Steam's achievement data.

A quirk worth knowing before you read the numbers below: Steam achievements for arenas 2–6 are named after the arena they unlock, not the one you just cleared. Beating the Catacombs boss grants the achievement “Pit” — because that's what it opens up. It reads like a mismatch at first; it isn't one.
