I've had so many cool fights I don't even know where to start. Monster hunts, duels, ambushes, even a sprawling 40+ battle (nowhere near as epic as some of the stuff in this thread). But seriously, no idea where to start, and most of them don't lend themselves very well to storytelling.
So, since I haven't played Adventure Mode in a while, I decided to open up DF and unretire my favorite adventurer. For those with long memories, that adventurer would be Cobar, the pale-eyed human legend from the Tenebrous Empires. Nearly every other adventurer I've ever played has been a miserable failure, so this guy is basically my claim to fame and go-to badass. He's a little older now, since I've built and lost a good dozen Fortresses since I last played this mode.
I'm so damn glad I picked him up again, because the first thing he went and did was fantastic. But fair warning, this might run long.
First let me set the stage: back when I used to play as Cobar, I had a 90-year-old female companion named Dema. She was old, she was athletic, she only had one hand, and she had more scars than a map has roads. I could tell you some INSANE shit about her, like the time she caught a spear with her teeth, but suffice it to say this old lady was fucking NUTS. I've never heard of a companion being more badass than the adventurer, but Dema ran on blood and murder. If she wasn't killing something with her bare hand, she wasn't happy. Thing is, though, Dema's been dead a long time. I won't go into details, since I don't have the screenshots to back it up, but she went out like a badass.
And it gets better: she had a sister named Cero Skullwoman. Married, forty-something, hard as nails, highly trained with a sword even though she didn't own one. So when I unretired Cobar in her village, imagine my surprise to find her in my house. I figured, well why not, and cooked up a sort of adventure scenario - far as I imagined it, Cero showed up and asked Cobar to help her go find an abandoned Fortress and loot it. And since he's got the wanderlust, he agreed. So, to mix things up a bit, I used advswap to take control of Cero and equipped her with a sword, shield, and some leather armor. Figured I'd let Cobar play himself. He can handle it, right? Sure, why not.
First night out in the wilderness in something like ten or eleven years, and Cobar's senses are still as sharp as ever. Cero woke up feeling uneasy and Cobar was already awake, standing near the campfire. And then the warlord and his cronies storm out of the trees, arrows flying.
Thing is, I'd forgotten that I'd equipped Cobar with a battleaxe since I'd grown bored with how easily he could kill things with his scimitar. He was pretty handy with the axe, but no master. But that hardly mattered, because when we charged out into the snow, every swing of that axe sent streaks of red spraying in every direction. First he rammed his shoulder into a Master Lasher and sent the guy flying. Then he took the arm off a spearman, and with the backswing swept the head clean off a crossbowman's shoulders. He moved forward another square, which gave the second Master Lasher time to swing his whip. It glanced cleanly off Cobar's shield and suddenly the Master Lasher was flying in two separate directions. The first Master Lasher didn't even have time to scramble back to his feet before Cobar stepped forward and bopped him on the head with the axe, just hard enough to shatter his skull into a thousand tiny pieces.
I missed most of this because I was holding the [<] arrow key, so all I saw was Cobar slam into a wave of high-level bandits and churn them into crimson butter goddamn instantly. By the time I yanked my finger off the [<] key like it was hot there were five men dead or soon-to-be-dead in the snow. Five men in less than five seconds.
The remaining three charged into the fray, probably screaming war cries. Cobar didn't even miss a beat, because he caved in the chest of the first guy, a bowman I think, then hacked the leg out from under an Axelord and punched the last poor sap right in the arm hard enough to break bones. The bowman with the broken lungs suffocated and/or passed out. Meanwhile, Cobar stood over the guy with the broken arm long enough to hack him into pieces with all the business-like calm of a butcher.
Cero got there in time to finish off the confused spearman, who was stumbling around painting names in the snow with blood from his stump arm. Then we took off after the one-legged Axelord, who had finally got it into his head that maybe this wasn't the place to be. He didn't make it far.
By this point there's blood all over the snow. Dead guys everywhere. It's been less than thirty seconds since the bandits revealed themselves and now there are body parts strewn halfway across the clearing. Cobar's leaving blood everywhere he walks, and I'm sitting in my chair laughing my ass off at how ridiculously efficient it all looked. So I switched back to him with body swap and suddenly my smile drops into a frown.
Somehow, during all of that, Cobar caught an arrow in the heart. I think it hit him before he could even reach the first bandit, which tells me that some of Dema's unkillable-ness must have rubbed off on him and manifested as he got older. Warnings are flashing, everything from 'pain' to 'heavy bleeding' to 'mortal wound' and probably even 'raging murderboner.'
Eh, no biggie. We went on to the Fortress, stripped it of weapons and valuables, and made it all the way to the capital city of a nearby human civilization without further trouble. The arrow didn't even leave a scar.
Bonus for whoever reads that wall of text:
A comic that perfectly describes Dwarf Fortress Adventure Mode.
