1.First of all the artifacts must be removed from the treasure deck, because every artifact can be found only in certain quests;
2.When a player search in the room than he must draw a card from the treasure deck, if he or she draws a monster card, then the enemy is "teleported" near the hero and he or she must immediately fight him;
3.When in a room there's a treasure chest and a player open it, he or she can't draw any treasure card, because the content of the chest is specified in the same quest. (For example: in the 2nd quest, "The rescue of Sir Ragnar", the chest in the room A is empty... and there's a trap too! In the room B, in the chest, there are 60 gold pieces);
I hope I solved your doubts!
