Trapped Undergarments (Don't Fear the Peeper)
Appearing as a normal set of frilly woman's lingerie, this set of underwear is set to explode if any male giant, monstrous humanoid, humanoid, or goblinoid touches these set of clothes. If, at the time, the garments are being worn when they are touched, the explosion does not harm the wearer. The explosion deals 1d4+10 fire damage in a 20 foot radius, with a successful Reflex save (DC 14) reducing this damage by half. Unfortunately (or fortunately), the underwear are destroyed in the process.
