- Activate to "reroll" all monsters in the room, replacing each with a different monster.
- You could get easiers monsters but you could also get harder monsters and even champions

- You can't reroll bosses, but you can reroll the monsters that the boss spawned
- Flying enemies can be replaced with non-flying enemies and become stuck behind a rock, making the room impossible to clear
