Roper: The Reverse Piercer

We had the stalactite monster. Now it’s time for the stalagmite monster!

Lore: A Living Trap

Dwelling within the caves of the Underdark, ropers conceal themselves within the stone and prey on unsuspecting passers by. It shares its territory with piercers, from whom they evolved.

And… that’s about it. The rest is just detailing how they hunt and what kinda loot they might carry. Which is fine; you gotta know that stuff so you can reward the players. But it doesn’t have all that much depth.

There’s not much you can do with this lore beyond an encounter in the Underdark. If you want to write a cool side quest or you need a monster for your next big bad, this is not the creature for you.

But hey! At least it looks cool.

Design: Stone with Tentacles

I’ve seen enough hentai to know where this is going…

“C’mere, babe! Give us a kiss!”

This is essentially a slightly cooler version of the piercer’s design. Which makes sense, given the lore. And honestly, that’s fine. It’s actually kinda cool to see monsters evolve into one another; it adds a cool sort of sense of progression.

Also, the tentacles make me really uncomfortable. I’ll count that as a good thing in this case.

This is a pretty good design. Yes, it’s basically a slightly different version of one we’ve already seen. But it’s still uniquely creepy and gross and interesting. So we’ll count this one as a positive.

Stats: A Carnivorous Lasso

I don’t know why I was expecting this monster to be so weak. I guess that just makes me its ideal prey; my dumbass would definitely underestimate it.

As you might expect from a monster disguising itself as a rock, the roper is pretty durable. Its AC sits at an even 20 and its HP is just shy of triple digits. Killing this guy might take some time.

It’s also got plenty of options for attacking. Its Bite attack does pretty much what you expect. Its Tendril doesn’t do damage, but it forces anyone hit by it to make a save; fail that and they’ll be grappled. While grappled, the roper can use its Reel action to pull them in, thus making them vulnerable to, you guessed it, the Bite attack.

That’s… actually a really cool and frightening combo. Why don’t more enemies do that?

Speaking of tendrils: those have their own HP. On top of that, they’re immune to poison and psychic damage, and destroying them does no damage to the roper itself. It does, however, reduce the number of tendrils it can attack with, making it easier to fight.

All of this can make for a pretty cool encounter! Throw a few of these, along with some piercers, at the players and suddenly you have a really hectic battle. How do they deal with being dragged around by the tendrils? Do they attack them or go straight for the main body? If done with care and precision, you can basically make it into a fight in a living mine field! That’s a rad idea!

Is it an epic boss fight? No. But it’s a pretty damn good normal fight.


This was a surprisingly strong entry. It’s lore is definitely one of the weakest that we’ve ever seen. But it’s design is fairly good and its stats are excellent! It may not be exceptional, but it’s pretty good!

With all that in mind, the Roper is going to #81 on the Best of the Bestiary!
