Here's mine:
First of all, I'm a ranger...
I was a noob (and still am) that had just boughten a bunch of scrolls and what not, to go on an Underworld party. Prior to that, I spent an hour or so just getting a few skills for the build I planned on using (that I found online): a trapper. I had never really used traps, because I didn't know how they worked, and they seemed quite slow. But I decided to use a trapper build, thinking the 'traps' were instantaneous debuffs (if that's the word) to enemy NPCs. I went for about an hour run standing behind my teammates using trap skills. I noticed I never really killed anything...
Later, when it was all over, I decided to look up traps some more, and decided to try them out more fluidly than I had before. I didn't know how they worked...
And so, when getting some Mandragors, I decided to test out a theory that putting down the traps, and drawing the creatures into the 'traps' (even though you can't see them) would set off the traps. I tried it, and when two Mandragor Slithers, ran into some traps I set, they got debuffed.

But anyways, don't forget to post your most embarrassing moment!
