There are tons of monster stat blocks available in the official WotC sourcebooks, and many of them are super fun to run. But, we couldn't resist. We've been homebrewing monster stat blocks that create new situations or provide unique challenges to players. Here are some of our favourites.
1. Adult Stone Dragon
With the recent release of Fizban's Treasury of Dragons, there is an absolute glut of great, interesting dragon stat blocks. We figured we'd throw our own entry into the ring. This bad boy is inspired by Robin Hobb's Farseer Trilogy, and is focused on the idea that it would be very difficult to get an attack through a stone dragon's hide.
2. Magic Eater
This creature is based off the Rust Monster, which is designed purely to annoy and frustrate anyone with a regular metal weapon. Turning that idea on its head, this monster does almost the same thing, except with magic weapons instead of regular ones. So, y'know, even more annoying and frustrating.
3. William Pony
Father of the famous Bill the Pony, whose legendary adventures are chronicled in the indie, underground trilogy entitled the Lord of the Rings, William is the more respectable and more dependable of the two. On a side note I completely forgot that I created William with the ability to speak, let alone speak Latin (which doesn't exist in DnD), so do with that what you will.
A horrifying, rideable spider. Need I say more?
5. Sucking Mass
Giving that good succ. No but seriously, difficult terrain is underutilized and the ability to create moveable difficult terrain, which makes it more difficult to approach and run from these creatures is fun. Also, throw them into a swamp or marshland and make them difficult to see? Terrifying.
Wort wort wort. That's not the accurate sound, but it is the right universe. I don't know what it is I love about enemies that make final, desperate, suicidal attempts to bring the players down with them... Actually never mind that is the thing that I love about enemies like this.
There are a few monsters that we've come up with. If you want more like them, sign up for our mailing list and you'll get one every week along with an NPC and an item. In the meantime, buy some dice! They're not free like these stat blocks, but they are a heck of a lot cooler.
