Not yet. I think mohrgs really are made to be mystery monsters rather than stronger skeletons. The zombies they create rise only after 1d4 nights, quite some time after they have been killed, and likely already buried. A mohrg prowling the night and staying out of sight can lead to people being found dead and then rising from their graves, or disappearing and then suddenly appearing in the streets as zombies days later. With the morgh being so obscure, and zombies being so generic, there is a very high chance that players investigating the random zombie appearances will have no clue what's going on until they finally corner the creature.
They appear in my homebrew conversions.did the doombat from the 1E FF ever appear anywhere after that? I always liked this monstrous powerful bat that could bite, whip you with it's tail, and emit a godawful sonic shriek. Plus, it was big enough to be ridden. I put doombats in quite a few places in my campaign worlds....
Yes, but the OP said monsters that have not returned in 5e yet, not just core 5e. See below, emphasis mine.(Which is not one of the core books.)
What are some of your favorite monsters that used to be part of the core rules, but aren't in 5E? What did you like about them? Have you ever used them? And would you like to see them return (core or otherwise)?
I think they appeared in 3/3.5e too, just not the original MM. But yes those would be nice to have again.I miss the Dragonspawn, the first batch of which were released in 4e’s Monster Manual. They were neat creatures to throw at players during dragon heavy campaigns.
