After a long career of killing beasts, bandits, night creatures, and other such things, my adventurer was finally called on to go and kill the dragon with 90+ kills who seemed to be the largest local threat. With my five recruited swordsmen and spearmen, I found the lair, which was just completely stuffed full of coins, dead bodies, and clothing, with the dragon in the middle of it. The fight was brutal, and the dragon breathed fire a few times in the process. I managed to avoid being directly hit by the fire at any point, but most of the contents of the cave caught on fire.
We defeated the dragon and then fled the cave, which was rapidly filling with smoke. I made it outside, appearing nearly undamaged, but as I was walking away my character started melting. I checked my inventory, nothing seemed to be on fire, but the melting and bleeding was getting worse. Several of my teammates spontaneously bled to death at this point. Thinking that perhaps some of my armor had become superheated, I removed all my armor and clothing and dropped everything. The melting and bleeding stopped, apparently just barely before I would have passed out from loss of blood.
I left the site and found a river to wash off and extinguish any remaining traces of fire in, narrowly escaping from hippos in the process. I returned to the site of the battle, figuring that now hours later it would be safe to retrieve my armor. My gear was scattered all over the place, of course. I picked up and started putting on my dropped armor, at which point I started melting and bleeding again. Apparently, my armor was now permanently hot enough to melt flesh. Either that, or dragon blood causes a melting syndrome now. So I dropped all my gear, declaring it cursed, returned to a nearby town, and retired the now badly injured and permanently scarred hero.
