Just a story that I somehow remembered two days ago, and I still keep smiling about it.
It was one of those nights when right after logging in I've got a message whether I'd join a group to do DPS. I knew the ones in the group from the guild, even went with them a few times, so I agreed. They told me that we are going to the pyramids. As an infrequent grouper (is that a word?) I knew next to nothing about these pyramids, except that they are some kind of an ancient Egypt alike pyramids with lots of undead.
This time, with me around, the group was strong enough to go to a place where they have never went before. In the way in we killed some weak and a few stronger monsters, I adjusted my tactic to use more fire. We also crossed a few traps - for example, big swinging rock blades. Then we arrived to the place. Cautiously, we went in.
As I usually need a few seconds to adjust to new places, I looked around. We stood in a corridor, with a stone walk in the middle, and huge, dark openings on both sides, where you could see something.. like.. I was zooming in .. acid lake? Wow. Something was moving in it. As you have guessed, these were some undead. They looked agitated, and were running towards a point I couldn't see.
I looked up to see where my group mates are, and realized that they got out of sight. Hurried after them - carefully - and found a monster standing in the corridor. Hmmm.. there is no other way.. where the hell are they then?
It is a bad habit to ignore the chat channel. But of course I did just that. Now, looking there, I realized that my group mates are fighting something down below, and were asking me to help. So I jumped down and joined the fight, but it was already a lost case.
After the wipe I asked what happened. I was told that while I was looking down, my group run ahead, into a trap, which pushed them into the opening on the side. Now I don't even remember who the other players were, or when this whole thing happened, but this surprise was so funny that I still remember this after all these years.
