Eliminating mundane, non-magical items from treasure hordes in 4e D&D was a great idea. But that doesn’t mean that the mundane treasures can’t be thrown in from time-to-time to create a more memorable encounter.
The way things were done in previous editions, where everything was stripped from fallen foes and monsters to sell off later may have made sense, but it hurt the game and slowed things down. I don’t know how many adventures I was a part of where an incredible amount of time was wasted gathering up long swords, suits of armor and other non-magical, every-day items from the corpses of the fallen foes and monsters. It often required an enormous amount of record-keeping and consumed valuable game time when we finally sold those items back to a local merchant. It unnecessarily side-tracked the game.
So in 4e if it’s not coins, jewels, art or magical items, the DM doesn’t describe it and the PCs don’t take it. It makes things simpler and, more importantly, faster. But just because we are now ignoring the mundane items doesn’t mean they don’t still exist. In some circumstances drawing attention to these now overlooked items can add some flare to an otherwise traditional encounter.
