* I may not make up a dungeon on the fly
** Especially when said dungeon is full of traps, also made on the fly
*** Doubly so if the dungeon is filled with Kobolds
**** Triply so if the dungeon is filled with Kobolds who are played in a smart manner.
***** Even more so if the party rogue is a cowardly kobold who stays in the back of the party that they picked up at the beginning of the dungeon who the rest of the kobolds want to kill for stealing all their nice stuff.
