Digging is one of the most important aspects of being an adventurer. When choosing a dig site always look for some archaeological landmarks. Digging near an ancient temple is always a good idea for obvious reasons. Digging in a troll pit, on the other hand, can be a health hazard and should be avoided unless "being eaten" is on your to-do list. On top of that, the fumes emitted from a troll pit are corrosive and usually melt both your shovel and your brain.
