Reveal Adjacent Unexplored Rooms: This Free Action is listed on the Act 1 side of the Torch Mat. Move the torch down one space on the Torch Mat to reveal all unexplored rooms immediately adjacent to your current room. If this reveals any Goblin/Minion Encounters, those tokens and cards are added to their respective rooms, but the hero does not lose Health.
For example, an ideal time to use this is when you are looking for a minion and cannot afford to lose Health by exploring to find it.
Note that an unrevealed room is considered to be adjacent only if there is an open corridor leading to it.
