This one frost wyrm (Genesis). I go in in hunting gear, after his bones for weapons and trophies and skin for precious deep hides. Strategy being the ol' lure out to avoid close quarters dragonfrost, hit and let bleed. I get him in the gut, severing an artery so I know he's done for. Time to make a run for it, except - he strikes like a rattlesnake and shatters my left foot, causing enormous pain. I land flat on my back, with a frost wyrm's head towering over me.
The next 15 minutes are something of a haze, but somehow I manage to crawl out of the cave before it fills with frost and roll out of the way of every single one of his vicious swipes, just moving my broken body across the ground as he's flailing murderously at me. I even manage to avoid his lethal blasts of frost with a good dose of luck, rolling to his side when he's firing, and land some further stabs on his body (I find that lashing at the enemy madly in defense helps you stay alive). Everything seems to be going well - but then he grabs a hold of my arm, which is mangled, and everything goes black. I'm sure I'm done for, but to my own surprise I wake up, one arm and one leg shattered, still in pain, in front of the maws of a dead frost wyrm.
Miraculously, there isn't even any nerve damage (other than loss of vision from one frost blast I couldn't dodge entirely). Everything seems like it will heal with time, but the wyrm bones must not decay. So I manage to drag my butchering tool over there and grab his bones and leather in the same hand, my bag being disintegrated in the fight. I fall asleep there, waiting to don my frost wyrm armor, admire my glorious scars of battle that will be added to an already-sizable collection of memories of wolves and titans, and share the legends.
I wake up just long enough to see with my damaged eyes a night creature use my skull for a soccer ball. Had I walked 5 more squares to actually INSIDE the cave...
