Unknown Room.jpg

Unknown Locations, also known as ? rooms, are a type of Map Location. When the player visits one of them, they may encounter an Event, a Monster, a Shop or a Treasure Room.


Upon entering the first ? room in an act, the chances of finding each type of encounter are:

The chance of finding each type of encounter increases whenever a ? room is visited and does not contain that type of encounter. For example, after visiting four ? rooms which do not contain shops, the chance of finding a shop in the next ? room will be 15%. If a shop is found, the shop chance will be reset back to 3%.
