In 1981 a Troll Named Grimtooth Set a Path for Today’s D&D Books

Grimtooth’s TrapsStarting in 1981, Flying Buffalo Games published a series of Grimtooth’s Traps books. They featured diagrams of traps that showed heroes on the verge of being folded, spindled, and mutilated. For instance, one sample shows a covered pit trap where the swinging cover severs a rope that drops a stone slab into the pit.

Dungeon Master: “As you advance down the tunnel, a trap door opens at your feet, dropping your rogue, Jasper the 8th, into a pit.”

Player: “Ha! Ring of feather fall!”

DM: “Ha! A two-ton stone slab drops on you, pushing you down the pit and crushing you to jelly! Do you have another character?”

Player: “Sigh. Say hello to Jasper the 9th.”

All the traps were ingenious, but very few could work in play.

Swing across chasmIn another example, a rope seems to offer an easy way to swing across a chasm, but at the end of the swing, the rope unspools several feet, flinging the victim into the wall, which is rigged to fire a volley of crossbow bolts into the victim’s body, before he drops into the underground river below, which I assume is full of sharks.

What paranoid adventurer would dare use a rope suspiciously ready for swinging across a chasm? And all adventurers in the world of Grimtooth will grow paranoid in a hurry. In practice, this trap gets bypassed without a second thought.

In most cases, even players who survive the traps will never notice the inventive mechanisms that make them function and that make them interesting. The traps could work in a sort of Toon/Dungeons & Dragons collision, where Wile-E-Coyote-like characters blunder into outrageous traps, only to reappear, without explanation, for the next scene.

Despite the traps’ minimal play value, Grimtooth’s Traps became a hit, leading to Traps Too, Traps Four, and Traps Ate. What made collections of useless traps top sellers?

“The traps were sometimes deadly and sometimes silly. They were often Rube Goldberg-esque, and not the sort of thing you could really use in an adventure,” Shannon Appelcline writes in Designers & Dragons. “However they were beautifully diagrammed and often very funny. The book was a joy to read.”

Much of the humor came from the books’ credited author, a troll named Grimtooth who relished inflicting inventive deaths on hapless dungeon delvers. “I feel that you’ll find this the most entertaining collection of traps you’ve ever laid eyes on. Besides, if you don’t like my book, I’ll rip your lungs out.” (Apparently, Grimtooth enjoyed Warren Zevon.) By flaunting the worst impulses of killer DMs, Grimtooth satirized a type familiar to roleplaying gamers in 1981.

Grimtooth first appeared on the cover of the fifth edition of Tunnels & Trolls. Then, in Sorcerer’s Apprentice magazine, editor Liz Danforth drew the troll as an icon for her “Trolltalk” column. Grimtooth gained his name in a reader contest.

While plotting humiliating ways to kill adventurers, Grimtooth offered some good advice. “A few of you numbskulls out there still haven’t caught on what it means to be a Game Master. A GM doesn’t slavishly follow anything—books, manuals, or edict from On High.” So when readers missed the joke and griped that the traps proved too deadly, Grimtooth invited tinkering. “Some of you have twisted ideas about how to administrate a dungeon, newfangled ideas about delvers escaping with their lives and stuff like that. Don’t ask me to to make my traps less deadly…change them yourselves.”

By the fourth volume, Grimtooth’s Traps Ate, the editors had abandoned any pretense that these traps might see play. Now the traps include dungeon basketball courts with mechanical arms that slam dunked characters, and deadly Christmas-themed rooms that killed adventurers pictured in Santa suits. (Why is volume 4 Traps Ate? The numbers 3, 5, 6, and 7 lack homonyms, so they were skipped.)

Grimtooth set the pattern for new Dungeons & Dragons books like Xanathar’s Guide to Everything. A D&D player can buy a Player’s Handbook and never need another book. Only DMs weary of the foes in the Monster Manual need another collection of monsters. But Wizards of the Coast aims to sell every D&D book to every D&D fan, so they lure buyers to books like Mordenkainen’s Tome of Foes by making the text entertaining. Part of the fun comes from humorous notes left by Xanathar and Mordenkainen, characters who owe much to Grimtooth.

As for the troll, his wicked engineering remains amusing. In Grimtooth’s Traps, The Addams Family meets Rube Goldberg.

Puzzle traps

In my previous post, I introduced gotcha traps, the first of my two categories of traps. This post reveals my second category.

puzzle traps

While characters must search for gotcha traps, puzzle traps always come with clues that signal their presence. With puzzle traps, the fun comes from either deciphering the clues to locate the trap or from working out a method to evade the trap, or both. The details of these traps matter. Because puzzle traps exist as tests of player ingenuity rather than character skill, the party’s rogue probably lacks any special advantage. Players rarely disable a puzzle trap with a quick check, rather they work out the game-world steps required to circumvent the threat. For more on the sort of game-world problem solving encouraged by puzzle traps, see my post, “Player skill without player frustration.”

Puzzle traps work like other obstacles that demand player ingenuity to bypass, but they bear an extra burden to be fair because of the danger to the characters. If an ordinary obstacle proves inscrutable, the game just slows until the players go another way—or the dungeon master has something come through the sealed door from the other side.

On the other hand, the stronger the warning signs that accompany a trap, the more you can increase the trap’s peril. If the players find a gem surround by a ring of blasted corpses, they will accept a certain lethality. Everyone loves to see a reckless instigator get zapped.

“Something about that gem just seems a little off to me.”

“Gee guys, something about that gem just seems a little off to me.”

To make puzzle traps work in the game, players must see evidence of their presence. Include clues that hint about the traps. Make the clues just subtle enough so the players either feel clever for figuring things or chagrined because they missed all the hints that now seem obvious. The last thing you want is players feeling they’re characters are dying because the DM wants to prove his superior ability to add arbitrary traps that kill characters.

sigil of levitationFor example, if the players spot a shaft going up with spikes at the top, they will fairly expect a trap that flings them up using, say, a sigil of levitation. But if the shaft is covered by a hidden trapdoor and players only find the smashed helmet of the last guy to crash up, the clue rates as too obscure.

Trap builders seldom advertise their work, but clues can come for other sources:

  • Earlier explorers leave signs that a trap has been triggered or bypassed. For example, the characters enter a room with spikes driven into the stone walls at ankle height. When triggered, the bottom of the floor opens to a pit. The spikes gave prior explorers a place to stand.
  • Disabled, tripped, or obvious examples of a trap appear earlier in the dungeon, revealing tell-tale signs of similar traps later on. For example, statues of warriors poised with real weapons line a passage. Midway down the passage, a decapitated skeleton reveals the two statues rigged to swing their swords. Later, the party finds a similarly decorated passage, but this time the trap triggers two statues bearing crossbows.
  • Maps, rumors, or hints reach the players from earlier expeditions or from other dungeon residents. These sorts of clues can bring social skills underground. Can the players trust a captive to lead them past a trap, or to lead them into one?
  • The dungeon’s builders built in puzzles or clues to test intruders’ cunning. For example, the entrance hall of the Tomb of Horrors includes a lengthy clue written into the floor. (Too bad Acererak’s obfuscated, ambiguous clues are almost as likely to send characters to doom as to success. Do avoid anything green though.)
  • Current denizens left evidence of the methods they use to bypass a trap. For example, players wade through a partially flooded passage and find a broad plank near a door. Unknown to the players, the door opens onto an unflooded stairway down. Opening the door causes a rush of water to sweep the the players down the stairs. Before opening the door, the dungeon’s inhabitants block the water by setting the plank across the bottom of the door, and then they step over the plank.
  • The trap gives signs of arming arming before it triggers. For example, someone steps on a floor tile and hears an audible click. This forces the rest of the party to search for a way to disarm or avoid the trap before the unlucky character raises a foot.

Usually, with puzzle traps, using the clues to decipher the nature of the trap leads to fairly simple countermeasures. Don’t stand there. Don’t touch that. But sometimes evading a trap can present as much of a puzzle as finding it. For example, consider my reverse pit, with the upward shaft and the sigil of levitation. To bypass the trap’s obstacle, players might need to secure someone with a rope to be raised to a passage half way up the shaft.

As I wrote this post, I scoured some classic, trap-filled dungeons looking for examples of the sort of puzzle traps that I recommend. Even though the classics served as my inspiration, I found few examples that suited my principles. Are my standards for trap design overly high? What published adventures contain puzzle traps such as the ones I recommend?

Related: Ars Lundi did a post on traps that reaches some of the same conclusions as I do. In the post, Ben Robbins calls the two categories zap traps and interactive traps. I like his term of “interactive traps” better than my term “puzzle traps.”

Looking back at Grimtooth’s Traps

Grimtooth’s TrapsStarting in 1981, Flying Buffalo Games published a series of Grimtooth’s Traps books.

Player: “Sigh. Say hello to Jasper the 9th.”

All the traps were ingenious; all were unusable in play.

Adding an extra mechanism—no matter how clever—to increase the lethality of a trap doesn’t add to the fun. It sends the players looking for a new dungeon master.

Swing across chasmIn another example, a rope seems to offer an easy way to swing across a chasm, but at the end of the swing, the rope unspools several feet, flinging the victim into the wall, which is rigged to fire a volley of crossbow bolts into the victim’s body, before he drops into the underground river below, which I assume is full of sharks—presumably, the flying, exploding air sharks from Arduin.

What paranoid adventurer would dare use a rope suspiciously ready for swinging across a chasm? And all adventurers in the world of Grimtooth will grow paranoid in a hurry. In practice, this trap gets bypassed without a second thought.

In most cases, even players who survive the traps will never notice the inventive mechanisms that make them function and that make them interesting.

As long as you do not dare using any of Grimtooth’s traps in play, you can enjoy the collections by chuckling over their wicked engineering. Here the Addams Family meets Rube Goldberg.
