Flood

Arena 6 of 6 in Blood Dungeon. We have not played far enough to describe the layout, enemies, or a boss name for it. What we can show is verified from Steam's achievement data.

Getting here

You reach Flood by defeating the boss in Tombs. That kill grants the achievement “Flood” — named after this arena, not the one you just cleared, because it's what that fight unlocks.

Where this sits in the run

By the time a run reaches Flood, only 79% of players have already dropped off — those who didn't beat Tombs's boss never see this arena. A low unlock rate on a later arena mostly means most players haven't reached that far yet, not that the arena itself is unusually hard. We are not making a difficulty claim from this number, and it is not a strategy guide — it's a population count.

What we don't have: a boss name, a map layout, an enemy list, or any strategy for Flood. We haven't played it enough to describe those honestly, so we're not guessing. The numbers above are the only claims we're making.
