Eyeless and weird, Destrachans are, I believe, unknown to D&D before 3rd Edition (one of a couple of new monsters that were decidedly odd, found in the Monster Manual). I have often come close to using them, but so far, never quite got chance - though they are definitely in the near future for at least one of the groups I GM for.
Anywho, here are my 5th Edition stats for this quite deadly enemy. Enjoy!
It's like a snapdragon and a leech made sweet forbidden love and had a horrible baby.
