Those passing a portal recieve a verily minor shock (no damage caused), that makes their hair stand up for hours, with static electricity for the whole day.

A wall of iron with a strong magnetic field. Naturally, most weapons and many other tools will be attracted to it, and once attached, will make it impossible to tear away with any strength. (Remember to add a monster so they have to fight, making their weapons touch the wall.)

Solution: slide the weapons along the wall until it looses its attracting power.

Especially handy if weapons were lost (e.g. to the magnetic wall above) comes the weapon-selling-machine. There is a slot for coins, and symbols of weapons and costs (1 copper for a small club. 3 coppers for a solid club. 1 silver for an iron-studded big club. 1 gold for a great spiked killer-club, and the like.) Having paid the requested cost, the machine makes a few weird noises, and opens, two mechanical arms producing the weapon.

The joke is, they bash with it the person that stands closest on their head. And withdraw. And they are pretty fast, curse them. If they keep trying, you could surprisingly open it on other sides, etc.


(Side note: the trap could be used against some strong enemy if they lure it back, and pay for the biggest club.)

The whole setup is based on the Fun with Invisibility trap. If silly traps are used, what suffers most (besides the ego) are the clothes. Once they are sufficiently damaged/dirty, let the heroes find clean clothes. If they choose to change their dress, the clothes will suddenly animate, and run away! (Preferably with a few valuable items.)

Following them, the clothes come to a pit and jump over it (the jump is only an illusion), and anyone following it will hit right into the invisible wall. Ouch. In the pit below await the clothes, and possibly many others.

"The endless hallway" has many variants. This one is a bit cheaper than spacetime-distorting magics; it uses a freely-moving band of rubber that moves as you walk. Once found out, the trap can be by-passed in various ways.

Using the same mechanism as a poison gas trap, this trap simply sprays a dye that permeates everything. It is nothing but annoying.

Of course, if you wanted to make it dangerous, it could be a death sentence to be in the near by city (city state) with such coloration. Used in royal tombs.

Mirror Mirror

You pass a mirror. Out of the corner of your eye, you see it move seperate from yourself. You get a couple of scoobydoo moments, but eventually you see the mirror image move in non reflective ways. They will taunt you. They will make fun of you. They will do things to embarass you. They will keep you distracted so something can come and get you... or you waste a lot of time.

The Ball Pit Trap
A pit lies concealed in the floor, artfully covered with a tasteful decorative rug. The players might even notice the delicate weave of thread through the rug, noting the almost sublime interplay of color and shape. As the rugs gives way, the PCs are dumped into a 20 foot deep pit filled with spongy balls.

These balls are a variety of bright and happy colors; Red, yellow, blue and green. The PCs have the usual task of getting out of the pit, but have to do so with the hinderance of being surrounded neck deep with these little balls.

Infamous Boulder Trap
The party are underground or in a tight fitting location. Theytravel up a slight incline and trigger the trap by pressure plate, trip wire, opening a side door with no room or hallway beyond, just a wall. A large, seemingly few ton boulder comes rolling down from a concealed section in the wall ahead of you.

The only option is to run the way you came but either due to the passage being smaller at the bottom (a possible door), or a pit trap slowing the crossing process, or a wall falling to block the path. The boulder rolls at a faster rate, with an odd lack of physical sound. No rumbling.

The players are pinned and the boulder comes crashing into them to smash open to reveal a cleaverly made paper boulder.

Many things can be within. I used this on my group and had clay jars of a sweet sticky liquid within that shattered and covered people with enough of it to be an inconvience only to later be assaulted by a hive of bees.

You could literaly tar and feather them in a similar manner. Clay pots of honey, tar, oil and then have a pit trap fall into a collection of feathers or something.

Fire Alarm Trap

This seems like a fire alarm, with a button with "FIRE" written in large red letters below.If pressed a jet of fire shoots out and scorches the hand of the one who presses the button.
