One of the challenges I’ve been encountering in my D&D game is the placement of treasure. Even in 5th edition, D&D still thrives on a steady drip of gold, gems, artwork and magical or semi-magical items. And placing those items in a natural-feeling way is hard.
Sure, you could just roll on the treasure tables for every enemy the PCs search but that will quickly get weird. As an experiment, I rolled on that table for every feasible encounter in my game so far. (That is: I didn’t roll for creatures like wolves or rats, but I did roll for everything that was at least smart enough to recognize that gold = value).
Had I used those results, the PCs would’ve entered an abandoned mine and gotten out with a magical scale mail (resists fire damage), 6 paintings, each worth a good chunk of cash, a small pile of gens, a few hundred gold pieces along with whatever weapons and armor they stole from their enemies. That would be for first level adventurers.
