About

Note: Treasures, monsters, and NPCs are generated randomly, so the information generated is pretty rough on the edges. Its supposed to be more of a guideline.
For use in your game consider the following options: changing or removing encounters, equiping NPCs, treasures listed belong to NPCs (i.e.: the treasure is not just lying around) or is hidden, removing treasure altogether, changing the alignment of NPCs, placing traps on specific locations, etc.

If you need something fancier, try WoTC's dungeon/adventure generator
