Description: Do you like your players very much? I hope not, because this one is a killer.
So there is some body of water - either a pool, or a waterfall, cascading down over a beautiful white-yellow statues with exquisite manufacture. Or perhaps a yellow-white necklace rests at the bottom of the pool. Perhaps these items are studded with gems (or what I like to call shrapnel)
What a wonderful use for magic aura!
Detection/Disarming: The thing about phosphorus is that it is extremely reactive upon contact with air. It will very quickly after being removed from the water dry off and begin to smoke. Shortly after that it will produce thick clouds of smoke only seconds before self igniting in the air, flinging large chunks of burning phosphorus everywhere. Conveniently once contacting flesh, it continues to burn!
Something small like a necklace or jewelry will do 3d8, minus 1d8 per round in a 10' radius, save for half, unless you are wearing it, in which case the funeral will be closed casket. Something large like a statue would do 7d8, minus 1d8 per round in a 40' radius, save for half.
(The Phosphorus Necklace is the classic implementation of this idea from Grimtooth's traps, a trademark of Flying Buffalo Inc. games)
