Anti-Paladin, think it was Issue #66.
My Paladin at the time had been annoyed by Kender for quite a while. When I read about the AP, talked to the GM and he let me do it… next session, we were in a city and I saw a bunch of Kender “working” the crowd’s pockets.
My Paladin just snapped. Rest of the party sat dumbfounded as began to slaughter Kender everywhere. I was ravenous! A running gag from the GM had been having a Kender pull a Breadbox out of nowhere (assumed bag of holding) anytime the party was looking for something and ask, “how about a breadbox”… well, this time I started collecting Kender finders and shoving them into a breadbox for the rest of the sessions.
Fortunately most of the party was neutral of some type and somehow we were able to keep the party functioning with a completely insane, newly minted Anti-Paladin who (whoever the evil god was) himself took on during his turning and granted him everything he had with (whoever the lawful good god(dess) was).
It was a lot of fun… and really after that, and with a different group, and in a different system (Iron Crown’s Rolemaster), it set me on the path to play Lazvon to incredibly high levels, though as a “Neutral Evil” who was actually nice to some folks as long as there was a means to his ends… much easier to play in pretty much any party (and no alignment constraints in that system - all in my back story and evolving story and a highly creative GM who ran one of the two best campaigns I have ever played in, other was GURPS space game with an equally talented GM).
