need to have the blessing of protection which is now good until level 39 pre second class change.
10 level difference can't be harmed by chaotic characters.
however, on siege grounds, or if you flag, you can be harmed.
now... what happens if a level 39 blessing of protection character attacks a red?
Why else would a dorf be participating in the vent much less a lvl 4 dorf for that matter. 3 words come to mind Clown Fish Hat ... NC wants every dorf to wear a clown fish hat to TW next weekend...
I have to agree with the others here. Why would you want to take a vita pop from somone else on a throw away dwarf. That is just wrong and basically you are being a jerk.
