Bait & Switch: Tempting the Greedy
by Jonathan Palmer
Every trapsmith knows that a trap is little more than a complicated piece of furniture or decoration until it springs to life and reminds people why no one comes down this way.

In a dungeon or community where many of the inhabitants are immune to poison, it’s not surprising to find that many of them coat their coinage in a thin film of contact poison.
