It’s a fairly common narrative device ever since Indiana Jones. Or the Tomb of Horrors, if you’re real old school about it. Anyway, you all know it: the ancient mausoleum filled with deadly traps.
Now, leaving aside boring, nitpicking questions like “how would ancient mechanisms still work and try to kill Indy 20 centuries later with zero maintenance ?”, let’s tackle the most basic question: were there ever tombs or necropolises incorporating traps designed to kill would be grave robbers ? I know some of the Pyramids had token mazes (for what good it did them, since grave robbers just tunnelled right through the sandstone) but what about the real D&D stuff like spike pits, rolling boulders, falling stone slabs, pressure plates, automated dart launchers or blade slingers, etc… ?
