Last night, as I crashed, I had an image in my head of a circle with five positions- one for each sense- and a monster hovering near each. The monsters killed using those senses of their prey. The list was like this:
sight - medusa
touch - carrion crawler (ghoul)
sound - sirens
smell - ghast
taste - ?
Okay, the ghast doesn't exactly kill you with smell, and I suppose the others aren't as direct as petrification either, but I still wonder, what would be a monster that kills you through taste? The most immediate idea that comes to my mind is some kind of poisonous fruit, but my creepier nature jumps to withered teats that are somehow addictive. How about you?
