Here's my tuppence:
Back in Ye Good Olde Days we were playing D&D 1st edition. We had a party of four: a Fighter, a Magic-user, an Elf (and for you youngsters: in those days, elf was both a race AND a character class, kind of like a bad fighter/mage multiclass thingie) and a Thief, which I played. We had adopted much stuff from Dragonlance book series, for example our mage was neutral (because there was only lawful, which sort of meant good, neutral and chaotic, which sort of meant evil) and thus wore a red robe (lawful wore whites and chaotic wore blacks). With this combo of adventurers, this is The Encounter I Will Never Forget:
Our party was at some port city, ready to sail off to another glorious adventure! Unfortunately the pirates decided to attack the city with five Big Vessels so we had to fight them! How unfortunate!
On the first round of combat our Magic-user spits out:
"I don't wanna do this. I'm depressed"
He then proceeded to the cabin of our ship and locked himself there for the rest of the battle!
OK so our spell flinging engine was out of the game. Fortunately we were high enough level for the Elf to hurl a Fireball to one of the ships - which was instantly set on fire. The Fighter was feeling cocky because he had acquired a dragon mount on the last adventure! How he tamed and reared it to carry him - we had come to the port city straight from the dragon lair - is beyond me. It just happened, as these things sometimes do.
So the Fighter flies off on his dragon to attack one of the pirate vessels, swinging his sword and yelling curses at the pirates. Unfortunately, there's a magic-user aboard every ship! The unfortunate Fighter doesn't even get to ship before their magic-user hits him with a Disintegrate spell! BOOM! The Fighter fails his save and is instantly turned into fine dust - and as it happens, so does his dragon mount too. They both sink into the seabed.
**INTERMISSION**
We later on went to get the Fighter's and the dragon's remains back from the seabed. While we were capable of ressurrecting the Fighter, the dragon was beyond our help. "It's remains have scattered", stated the GM. How the Fighter's remains were all in the same place - and how the Disintegrate affected BOTH the Fighter and his mount - well, it just happened, as these things sometimes do..
**INTERMISSION ENDS**
And the battle continues! My Thief runs to our ship and tries to persuade the Magic-user from his cabin. No luck. At the same time the Elf throws an Ice Storm -spell to another pirate ship. It stucks to it place and begins to sink (!). At this point the pirates decide to retreat. To cut it short, they never do because we annihilate them!
Except for one ship.
This one ship rises to the air and starts to fly off! Fortunately, my Thief has a Ring of Flying so I'm off to chase them! I fly a little bit faster than the ship and reach it in a few rounds. They don't see me coming and I start looking for the magic-user. I find him concentrating hard on the spell that keeps the ship afloat. I then proceed to load my crossbow, take aim at him and BOO-YAY! A DIRECT HIT!
The Magic-user dies. His spell fails. The ship falls from the sky, crashes to an island, everybody dies!
I fly off to examine the wreckage. And what do I find? 200 000 GOLD PIECES! It's a big money for sure. But, in the first edition, you got XP's for finding gold pieces - 1 XP for 1 GP. So I got 200 000 XP's (+ some more from the "defeated" crew of the ship) and leveled up. Twice. At the same time.
So I return to the port where the remaining party is finishing the battle. And then the unexpected happens. Our Magic-user emerges from his cabin wearing BLACK ROBES - denoting that he is now chaotic! And then the following conversation ensues:
Elf: So you became chaotic?
Magic-user: Yeah.
Elf: OK.
End of alignment changing conversation! It was never brought up again!
Oh, sometimes I miss the old times... :)
