Level Changes

Roll 3d6.  (Need a die roller?)  Research re-rolls may be used.

3-4 …this route leads off into an area of an entirely different type – effectively, another Dungeon, though your Goal may still be found here. Start up a new, blank Dungeon Record Sheet, and roll for a new Dungeon Type and Dungeon Theme. The Monster Ecology will likely be different, too!
5-6 1d6+1 levels down.
7-8 …two levels down.
9-11 …one level down.
12-13 …one level up.   If you reach level 0, roll for a Dungeon Entrance.
14-15 … two levels up.  If you reach level 0, roll for a Dungeon Entrance.
16 …1d6+1 levels up.  If you reach level 0, roll for a Dungeon Entrance.
17-18 …this route leads off into an area of an entirely different type – effectively, another Dungeon, though your Goal may still be found here. Start up a new, blank Dungeon Record Sheet, and roll for a new Dungeon Type and Dungeon Theme. The Monster Ecology will likely be different, too!
