I'm converting the classic AD&D adventure, S2: White Plume Mountain (by Lawrence Schick), into my dungeon crawl system as part of my next article under the Protection from Chaos series. In doing so, I had to recreate the Kelpie, a carnivorous plant that appears as a beautiful woman and lures men to their deaths. The creature was introduced to the world of D&D by this adventure, and I couldn't find it in 4th edition format anywhere else, so with a little inspiration from a couple of classic D&D monsters re-skinned to match the traits of the Kelpie, I created it myself. Here it is: The Kelpie. Try to resist.
