1. Pathfinder, but basically, yeah
2. Chaotic Neutral, the best alignment for going, "FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUCK YOUUUUUUUUUUUUUU!"
3. Eh, not really. As far as I know, my group and I are sticking with Pathfinder.
4. We mostly do homebrew settings, but they're pretty much Golarion-like.
5. My old 3.5 crew were in the Grey Wastes for some horrible reason and we were assaulted by a horde of spiked devils. After taking a pummeling from my spell slinging wizard, one of them decided to impale me on his body. This impaling dropped me into the negative hp. So our cleric kept casting heal on me each turn as the fighter, the barbarian and rogue wailed on the things as they passed me back and forth impaling me each turn. I literally went through my entire hp total almost half a dozen times in so many turns.
My teammates fought valiantly for my crotchety wizard who had spent the year and a half we'd be doing this adventure treating them like inferior poop. As thanks for their valour, in the next battle we'd ended up against a corpse gatherer thing. A construct immune to magic that put an epic beating on us. Well, them anyway. I cast invisibility and fly on myself and took off at top speed like the true hero I was.
Alternatively, it was a day where a lot of people no-showed so our DM came up with the meanest, nastiest thing he could think of for my wizard and my friend's rogue. We were investigating a mysterious cottage that appeared outside of the settlement camp our party had been staying in during our campaign. After solving a few puzzles that required the specific skills of both a super genius wizard and a nimble as fuck halfling, we came face to face with the cottage's (fortress on the inside) owner, a rather whimsical lich who gave us one chance at not being his new decorations.
He pulled out the deck of many things. Now, my character is smart, curious and completely sure of his superiority over most mortals (by this point his intelligence was higher than most demigods) to the point that he'd gone on to invent an entire line of brain busting strategy board games that had taken the homeland by storm (we did some fucking weird shit) but he'd never been what you'd call lucky. The lich wanted to play a game, we take turns drawing from the deck until someone either refused or was incapable of drawing any more cards. If we won, we'd be free to go, if we lost, well, he'd deal with us most comically. The rogue was excited, Frednando, the wizard, me, was less so.
We all drew two cards. The lich drew the one that increased your XP and caused you to draw more cards. He gained tens of thousands of xp this way through the most miraculously lucky draws of all time. He also drew a card that changed his alignment, to what, we wouldn't get the idea until later. The rogue, drew a card that granted him a weapon and a card that would cause a close ally to turn on him, this, being something that he'd be able to deal with later and not now, he was excited. I drew both black aces. All of my gear was destroyed and my fucking very body and soul were locked away as an imprison spell (the rescue of Frednando would be an epic multi-week adventure that would come later).
At this point, the lich had suddenly had a change of heart. He gave the rogue some healing potions he had lying around, gave him instructions on how he and the rest of our party could rescue me and sent him on his way before vowing to right the wrongs he had committed throughout his millenia of evil. The fucker had randomly changed from chaotic evil to lawful good.
When the rogue got back to the settlement, he decided to go visit the settlement's archmage, one of the leaders of the expedition, to find out how rad the new weapon he had been granted by the deck was. He was shown up to the archmage's laboratory, without even being made to wait, which was a little unusual. Upon coming face to face with the archmage, was put into a hold person spell where the archmage recounted how he had recently come across evidence of the rogue's nefarious activity (the rogue had talked his way into taking the lead investigator role in routing out the thieves guild that had taken up shop in the settlement, upon dismantling of the guild, the rogue had set himself up as the new boss and had been behind a huge crime spree while maintaining the guise of trying to stop it) and how he had been found guilty and sentenced in absentia.
This is when the archmage disintegrated the rogue.
Deck of Many Things man, fuck.
