I had moved Probably about 70-80 miles north giving me a few miles closer & many minutes shorter southbound commute to work. Somewhere around 2006 or so I got invited to join a 2e group being (re)started by a friend of a friend & met up with said group.
A few of us were there early & started talking about pasty experiences. One of those stories was the time Billy's paladin fell.... Billy had been playing the first paladin anyone in the group had played because they had just recently come out & were hard to qualify for with must be a human who had a high stat in multiple attribs & it was one of the first couple sessions with said paladin so nobody really knew what to expect...
That newness & unfamiliarity is important, don't forget it. During the adventure Billy finds a cursed I forget... a ring belt helmet or maybe necklace] of alignment changing. Not really being sure of what would happen & not wanting to blab it to the table working it out, the GM took Billy aside to work out what happens when a Lawful good paladin puts on a magic item that changes said paladin to being Chaotic Evil.
GM was horrified at the answer & tried to convince Billy that he could probably somehow get the curse broken & work back to LG... Billy said that he had a better idea & asked the GM to keep quiet about what they talked about
Billy & the GM get back to the table with the GM looking a bit worried & Billy maybe excited or something but everyone could tell he had news he wanted to share....
"My god has given me a vision about an incredible treasure room we missed" Billy tells the suddenly excited group. After a bit of discussion about the vision it weas clear to the party that there was a secret passage hidden in the wall of a pit trap back there behind an illusion that looks like the same stone.
One by one Billy convinced the entire group to jump into a pit trap, bounce off the solid wall, & agree that the last guy
just missed it. One by one the GM tried to convince the party that they don't see anything to back up what Billy is claiming & that the bodies of their fellow party members at the bottom really do look like an exact match for what they would expect if that PC had leapt into & died the pit trap. Billy citing his special paladin powers & link to his god was
very convincing though & eventually used a rope to safely loot the bodies before leaving the dungeon.
Everyone had a blast & many laughs were had both at the time and years later with one of the players who was there backing up the fun both at the time and how the whole group (billy included) made new PCs who were related to/familiar with the old ones & heard about the evil paladin that needs to be stopped... as soon they were a bit stronger for the next adventure.
