12. The Pit Trap Illusion

This room is completely empty except for a large chest in the far south corner. There is nothing at all in the chest; it's meant to lure unsuspecting adventurers to their doom. If one of the characters enters the room they will fall into a pit trap and take 1d6 falling plus 1d6 spike points of damage unless they save vs. Death Ray (add DEX bonus to roll). The floor over the pit is an illusion, so normal trap detection will not work; however, a Magic- user will have a 1 in 1d6 chance of spotting the illusion. A detect magic spell would also detect the illusion.
