Unknown Room

Unknown Location, also known as ? rooms, is a map location. When the character visits this location, he or she may encounter an Event, Monster, Shop or Treasure Room.


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

  • Monster: 10%
  • Treasure: 2%
  • Shop: 3%
  • Elite: 10% (with Deadly Events modifier only, floor 6 and above)
  • Event: if no other encounter is found

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%.
