Fiery Field (Japanese: 炎の大地 Blazing Land) is a dungeon in Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team and Pokémon Mystery Dungeon: Rescue Team DX. It is home to Entei and contains 30 floors. HM Surf is required to enter and the game will be saved compulsorily before entering.
Fiery Field is the first dungeon in the quest for the Mirage Pokémon. Once Entei is defeated, it will turn the Clear Wing into the Red Wing and allow access to the Lightning Field.
Fire Stones can be found on the ground on 29F. In DX, these are replaced with Evolution Crystals.
In Mystery Dungeon DX, this dungeon may contain an Mystery House, which can be opened with an Invitation bought from the Kecleon Shop.
