Do you have some great (or terrible) trap ideas that you've run or encountered? Let us know here in the comments, or join the TPT Discord server and share them there!

I love using Silent Image and Minor Illusion to trick enemies. Bridges over holes? Looney toons style door painted on the wall. Making the stairs sliiightly higher to mess with someone's depth perception and potentially trip them. Myahaha.

Had a trap I called the trash room. It was a 4x6 room that had a steel lined door. When activated they had x number of rounds to get out, or Alchemists fire would come out of the ceiling for something like 6 rounds.

The good old hall and conveyer belt trick. There’s a hall with a hidden conveyer belt in the floor with a door at the end of it. When the party enter they just can’t move closer to the door.

I'm quite fond of Runesmith's "Most Annoying Dungeon"'s illusion-disguised pitfalls. The way it's set up, it looks like there's randomly spaced pitfalls. But because of the illusions, some of the visible pitfalls aren't real, some of the real ones are disguised as safe tiles, and the actual pattern is "safe-pit-safe-pit". It's a bit trial-and-error-y, sure, but it becomes a bit of a pattern recognition thing with the side effect of having a bit of a red herring to it - sure, you can try dispelling the illusions... oh wait, you can't, because 3 inches above the illusion spell there's an anti-magic field that goes up to the ceiling of the hallway. So the party either has to brute-force the illusions or, if they're smart enough, brute-force the first couple and find the pattern.

Had to cancel my next session tomorrow due to sickness. This video makes me happy we did. Time to place some traps. I'm gonna straight up steal that banshee jar idea. 🤣

Ayeeeee love a good Tavern story

OP of the last story of the video here, I guess I forgot to clarify for the story submission version of this tale that the mud was considered a "trap" because the hag had altered terrain throughout her lair to do reactive stuff like that. Hence, the roll they had to make for it to not be considered difficult terrain.

I had a trap that ended up being a horrid idea. It was an old-school Tomb of Horrors style thinking player's trap. A large, perfectly cubic room with different numbers of windows on various sides. In the middle sits a dungeon key artifact needed to progress. It is protected by a magical force field. The idea is to solve the puzzle underneath the pedestal that the artifact is being kept in to deactivate the field. The room however has the worst possible turnout if you try to shortcut the puzzle. Casting "Dispel Magic" in the room will cause the dramatically enlarged Adamantine d6 to return to its normal size... generally at least some of the party inside. The key will slip through the window it's perched on, but anyone in side will be turned into hot tomato soup. 😲 I have still yet to find a party that I thought could handle this type of trap without calling foul. 😓 A sinister DM can dream, though.

Not the worst one, but one I'm a bit sick of at this point is magical alarm that can't be disarmed without triggering it (usually triggers a fight against some constructs or summons). Supposedly, we can teleport through it, but we never have enough teleportation (because why would we), and I'm not sure if we wouldn't get stuck if we did it. I mean, the problem is not a trap itself but the fact that it became very old very fast. I guess the DM uses it for the sick of verisimilitude, but it isn't fun to deal with after all, especially if you already know what it is pretty well.

Maybe the disconnecting player was a coincidence? I've had occasions where whole relationships hinged on the frequency and/or involvement of players in their RPGs because they were on the verge of obsession/addiction, and once I had a player get into a shouting match with his wife on the phone because he hadn't told her that he would be out playing this evening and had made a promise beforehand to limit his playing to twice a week. And that was live, in-person. I can imagibe that a thing like that happens all the time if you're obsessively playing online, so maybe the player didn't WANT to leave, but had to because their parents, SO, roommate, whoever told them to or blocked the people/campaign themself.

The hypnotic hallway might get me to duck out of a campaign. I _hate_ mind control bullsh, and having an effect like that with no saving throw just speaks of an intense disrespect for the players' agency. How much more mind bullsh will come up in that campaign? Is it worth dealing with?
