Hmm... Dwarves made entirely out of ice? I'm intrigued.
Adventuring as a corrupt is odd, to say the least. I sold some extra sunmetal armor, and when I returned to the shop a few minutes later, the shopkeeper had placed it on the tables, igniting everything else in the shop.
Corrupts' bones apparently cannot be broken, they just bend instead, leading to odd situations. I got into a fight with a bandit wrestler, and he kept "bend[ing] your left ankle, shattering the darkmetal and bending the darksteel!" This went on until I killed him; he refused to let go of my ankle, presumably because the game did not see it as "broken."
Another odd feature of corrupts is that most of the bandit groups I've come across have not been hostile towards me, letting me talk to and recruit them. This lead to the odd situation of me having a group of eight or so goblins calmly follow me into a fortress. I talked to the lady, got a quest to kill a hill titan, then my goblin compadres rushed in and slaughtered her.
Butchering corrupts produces things like "corrupt bones" and "corrupt fat." This is normal, apparently, as the materials are just named after the creature they came from. I just found it to be pretty funny.
Finally, I had to change the backpack reaction I posted earlier, as it seems that a sunmetal backpack will eventually melt any metal object placed in it. Oddly, flammable objects were fine until I took them out. Backpacks made of "sunmetal-safe" metals, like darkmetal, are perfectly fine, and will not conduct the corrupts' heat to objects placed within them, at least according to the testing I've done so far.
