Me: There are three big, ugly orcs at the end of the tunnel...
Players: It's an Undead Orc Lich Lycanthrope Mage!
Is that a thing? If it is, wouldn't that monster be completely insane?
It might make the GM's job easier if I just went with what the party said. They come up with scarier monsters than I do. It's also important to note the alleged 'orcolich' survived a double knock-back and made his ToP check, furthering the assumption it was more than a normal orc.
I found a fun Orc Name Generator! Because monsters have names, too. ;)
