- It all starts with a room, the room is seperated into halves by a thin glass wall. The side with the only door (where the PCs must enter) has 2 torches mounted on the wall. Across the room, on the other side of the glass, a treasure chest can be seen but everything of the other side of the glass looks a little “foggy”. The PCs with almost always break the glass, causing a mass amout of Combustible Gas to rush towards the PCs and ignite on contact with the torches, i assume this must hurt. It can all be avoided by simply putting out the torches though.

Simple and yet so good-a trap that can remain untouched by time.A good trap for an underground tomb.

A good idea. And yeah, it won't go bad over time (with a perfect seal) but it's only one-use... also, you want to make sure the treasure is fireproof perhaps.

Good, but still too short.
I love these little riddles. And a riddle might just make this post better.
Something that could eventually make the PC's figure out the solution.
Not too easy though, no not at all preciousss.
A good solid idea, i will use it as soon as I get a chanse.

Deleted my vote(a 3.0).
I tried this trap in my game and it worked really good. 15min of good ole RP fun.
A simple solid post that works this well in game deserves a higher vote.
Easy to expand on, easy to throw in a few details while playing it out as well.
In my game it even provided a small plot hook as well.
I produce a... 4.0.
Great trap.

The treasure might not be as valuable as it appeared, but to a medieval tech base, the glass itself would be valuable. A room where a valuable, artistically crafted window was on display might form such a trap without any intent on the part of the room's creator. Of course, flammable gas is unlikely in such an instance, but bad air is likely. For example, lamps may have been left behind the glass, burning until they used up all the oxygen.

Why this is so familiar it hurts. You have explained yourself and I am glad it got out there. Excellent trap idea.

Wonderful idea, no matter who came up with it. Kudos to Railus and Pieh.

Sounds great, I like it.
I'd to do this if I were the adventurer though.

Update: Added Railus as a contributor. He was the original inventor of the trap, I posted this in a trap list in the forum and it got converted to a normal submission, hence the shortness. Just giving credit where credit is due, I'm glad you've all enjoyed it. It was fun to encounter (especially the second time, when we didn't blow up).

I have to vote for this because it is such a simplistic but fun trap that I will undoubtedly use it in the future without recognizing where I learned it from.

This one is nice and simple, and does not require bending over backwards to justify its existence, especially if transferred to a slightly higher tech level.
That the glass has an uncommonly tight seal could perhaps be explained by magic used in its construction.

Elegant, with ample chance for players to noodle things out.
