Wall of text incoming!
@Drag/Tehs: They got us surrounded boys! Time for our final stand...I say you fight it out, then run if things go bad. You can run-said creature can't move fast, or even open the door you used to get in here.
Your facing what it roughly a Golem, that eats metal of course, but being a skeleton it more likely absorbs it rather than physically chewing on it, I guess. You have crappy wooden swords, but it should be enough...dismember it at the legs-it can't hurt you very much without legs...so bash it to pieces, and leave it to stare at the ceiling for eternity lol. A nice idea might be to lure into the doorway then close it on it, hopefully damaging it. I can't imagine said creature moving very fast without falling apart, nor being very intelligent. Use this to your advantage. Lure it into a trap with some tasty metal, and bash it apart. Ironic, if I was to join you guys, my staff, which is made of stone, would be quite useful here. You could try using your torches on the monster-if it feels pain, awesome. If not, you've got an angry steel monster with heated fists. Drag, you got strengthen metal? Try to make it the
opposite way, to weaken metal. It's a long shot, but it is worth it. In conclusion, this monster is nearly an nearly unstoppable force-if it's like a bronze golem, only removing the head will kill it permanently, and it will never tire or feel any wounds past a critical hit dismemberment.
That's all I can say, without some kind of monster lore roll-I'm not sure if its literally made of rusted metal, or a metal golem that became rusted, or a living creature that eats rust and deposits it on it's skin as a natural defense.
Then again, you could run away...that's a plan! This thing eats metal, so it will chase Dragnar to Hell and back as long as he is carrying his iron sword and breastplate, other than that it is merely defending its territory-again, this is a guess, this thing might be evil, and kill for fun. The breastplate is far more resistant than any of your iron to rust, remember that. At worst Drag might look like the statue of liberty. Drop the goods and back away slowly?
ActionsSneak back to the "special crafts" room, shut the door and stack some bins against it so no one can open it without a alerting me, hopefully.
If I am pursued, lead them into the traps and Curse them from afar, preferably with some kind of mental damage like, "your brain is on fire!" from Nethack's Kobold Shamans. If I get a successful spell off, can you add it to my spell list, btw?
If they retreat, take the time to loot any bodies of trinkets, gold, gem encrusted socks etc before moving on.
If they continue to pursue me, continue in the direction I last saw Drag and Tehs go, trying to get their help.
If I get to safety, eat my bread and get some sleep.
