Here is another installment of exTRAPaganza, our Thursday over-the-top trap series.
There are traps everywhere. Wires run from doors into the walls. Glyphs and other magical markings mark doors, chests, etc. Blades are hidden under desks and in locks. Needles can be seen.
All of the traps have already been set off and not reset. They will be detected everywhere though, and only appear to be inactive if the DC to detect them is exceeded by 10 on the check.
