Monsters, Rated: Pop-up Enemies with a Death Spiral for Dungeon World

Comments None

It’s no secret that I love the world’s 1st RPG (if you don’t count “Fantasy Wargaming”) Tunnels & Trolls by Ken St. Andre. There’s a lot to love about it, but one of its cool features is that the referee can create monsters on the fly with nothing but a vivid idea and a single Monster Rating.

The Monster Rating (MR) in T&T is a number that determines how easy or hard it is to fight the monster, how hard the monster hits, and how much damage it can take in combat. It’s possible to add more mechanics to monsters, like armor or special attacks, but the Monster Rating is all you need: The rest is fictional positioning—describing how the monster behaves and moves!

Another aspect of the Monster Rating in classic T&T is that once a monster takes damage, its attacks and defenses suffer, creating a death spiral. The effect of this is that you can start out with a monster so terrifying that the heroes don’t stand a chance if they take it head on—but if they are clever, creative, and lucky, they might cut it down to size. This rewards planning, teamwork, and imagination in spades, and it gives players a rush when they succeed at getting the monster bloody or wearing it out before engaging it directly.

Monsters in Dungeon World are almost entirely composed of fictional positioning too. But making a monster has a few more steps than in classic T&T.

I’ve toyed around with the idea of using a Monster Rating for monsters Dungeon World a few times, but I never landed on something that felt right. But today, I found this note in an old notebook and it clicked together. I think it might work.

Here’s the basic idea: When you create a monster, give it a Monster Rating from 1–44. MR 3 would be your average peasant, and MR 30 would be among the most shocking and colossal monsters in the game. The Monster Rating stands for the monster’s Hit Points, and you derive a monster’s damage dice from its MR as follows:

MR Damage dice
1–4 w[2d6] (roll 2d6 and take the worse result)
5–9 1d6
10–14 2d6
15–19 3d6
20–24 3d6+1
25–29 3d6+2
30–34 3d6+3
+5 +1 damage

The formula is this: Divide the MR by 5 and round down to get its damage dice. If that number is higher than 3, add +1 damage for each multiple of 5 instead of adding a damage die. If this would give you zero damage dice, roll 2d6 and take the worse result instead. So, a monster rated at 33 would roll 3d6+3 damage. Clear and simple.

The monster’s Impulse, Tags, Moves, and other qualities would be set in the normal way.

This gives you both aspects of T&T monsters: Create monsters more rapidly, on the fly, as you need them; and monsters will have a handsome death spiral your mom will be proud of.

The Monster Rater Generator

Assigning a Monster Rating is more of an art than a science. You should just pick a number from 1–44 based on the guideline above, then assign moves and qualities as usual.

But for good measure, here’s the Dungeon World monster questionnaire, adapted to give you a piping hot Monster Rating instead of Hit Points and damage dice. The original text is, of course, written by Sage LaTorra and Adam Koebel and used with their permission under the Creative Commons Attribution 3.0 Unported License. The Monster Ratings are by me.

If you end up with a Monster Rating lower than 1, use 1 instead—but you may wish to let “MR 1” represent a swarm or gang of the creatures. Or you could set the MR to 1, but reduce the damage dice to d4s.

With Descriptive Damage…

An earlier draft of this article offered a way to track monster wounds without logging every single Hit Point. If that appeals to you, here’s what to do:

Forget about the Monster Rating, and just mark the monster’s current damage dice. If a monster takes less than 3 damage from an attack after armor, simply narrate how it is knocked back, stunned, or whatever. When a monster takes at least 3 hits of damage (after armor), downgrade it’s damage dice by one level for every multiple of 3 damage that gets past its armor.

So a wizard who hits the giant wildebeest (MR 16, 3d6 damage) for 5 damage would knock it down to 2d6 damage. A Barbarian hitting another wildebeest for 9 damage will kill it.

Some people won’t like this because it makes lower-range damage less mechanically meaningful.

That’s it for Monster Ratings.

Use it if you dare. Let me know what you think!
