Yellow Line Reward Room

Train car full of suitcase shelves, Grapple porters.

The Yellow Line Reward Room debuts in book 3 of Dungeon Crawler Carl as a distinctive train-car chamber packed with suitcase shelves and patrolled by Grapple porters. This mobile loot vault offers crawlers a rare chance to scavenge supplies while navigating the dangers of the third floor’s transit system. Its compact, high-risk design underscores the escalating complexity of reward mechanics as the dungeon’s challenges intensify.
