Gauntlet Room is a room in The Gauntlet, a mod for The Binding of Isaac.
Generation rules
Has a default 1% chance to generate on a floor.
The chance can be increased by 10% by completing a Challenge Room, or by 25% by completing a Boss Challenge Room.
Completing a Gauntlet Room sets the chance to 1%, and cannot be increased by any means.
Cannot generate on the first floor of Chapter 1, or in Chapter 6 and later.
Room behavior
Shortly after entering a Gauntlet Room, all doors close, and Isaac will be forced to clear 5 Challenge Room waves in order to clear the room.
The waves gradually increase in difficulty, and the last 2 waves will be Boss Challenge Room waves.
Getting hit during a wave will teleport Isaac into a neighbouring room, and the room will start over when re-entering it.
Each wave cleared will charge Isaac's active item by 1.
Clearing all 5 waves will spawn an item from the Gauntlet Room pool, and re-entering the room will no longer trigger waves.
