http://forum.yeoldeinn.com/viewtopic.php?f=165&t=1392I’ve found that about traps, it is better if you can say that “they probably are in the marked spot, but until you do a search for traps you should roll one dice for each step you do on each unexplored square. If you score 1 the trap is on your current square.”
This is not very disturbing and causes tension. You afraid to move many squares if you know that you can roll a 1.
Also, you can say that “you describe your entire move and roll that many D6 as the number of unexplored squares you have pass. Roll all the dices together and check them from left to right to see if you roll any 1s”. For example, if you find a 1 on the first dice from left, the trap was on your first step, if you find a 1 on the second from left, it’s on the second. It’s almost impossible for two dices to be in a position that you can’t tell which is more left or right. This will reduce the number of rolls to just one with more dices.
