You will need: a deck of playing cards, a coin, a d%, a d10, and something to work as a d3 To use this system you draw a card from the deck and put it aside, draw two more cards and put them aside, if you drew more than one "trap card" you discard all but one "trap card" if you end up with more than one face card of the same type (for instance two kings) discard to one of those face card types, at this point you must keep drawing (following the same rules from above) until you have three number cards under 8 those are you room's dimensions, other than that it's pretty self explanitory Rooms: Face = Monster in room

         Ace = Monster with treasure
         King = Monster with minions
         Queen = Mutated monster
         Jack = Monster with magical
         weapons/abilities

Numbers from 8-10 = room with trap

Numbers from 2-7 = Length/width/height of room

          7 = roll a percent die
          6 = 35 ft
          5 = 30 ft
          4 = 25 ft
          3 = 20 ft
          2 = 15 ft


Monsters: roll a d3 1 = MM 2 = MM2 3 = MM3 Then roll 2d100 and use the monster on that page, if that page contains no monsters/does not exist, re-roll.
