Is there a book with a set of tables to help procedurally create new and unique mythos monsters?
I have been thinking of creating a set of tables to create unique mythos monsters, entities, and gods, or at least serve as inspiration for me. Although I love the exisiting mythos monsters, and the Malleus Monstrorum, but I like the idea that each creature or entity is different, and have their own quirks, characterisitics, and abilities, and should look unique.
Is there a book or site out there that already does this? I have seen something similar in the most excellent Tome of Adventure Design, but I would like something with more of an eldritch or Great Old One tone to it.
I am happy to look at any book or website that you think would be useful.
Many thanks in advance!
