Dungeon Floor 4 — The Iron Tangle
Overview
Floor 4 is called "The Iron Tangle" — a vast underground rail network of hundreds of named stations connected by double-sided "noodle" track tubes. The floor's central mechanic is the Rev-Up Vitamin Shot addiction cycle, which transforms mobs through three DT withdrawal stages culminating in the Krakaren parasite endgame.
First Appearance
Book 3, Chapter 1
Structure
The track system uses double-sided "noodles" — each tube has an upper (normal orientation) and inverted lower side, both functional and inhabited. Named trains, viewed from above, trace the Iron Tangle Syndicate logo. Crawlable space exists between the parallel noodles.
Six Station Mimics occupied key hub stations, concealing stairwells. Province bosses guarded stairwells at Stations 36 (inverted side) and 48.
