Can gnome necro do crushbone belts/pads quests?
 

i have a gnome necromancer, worked up faction with dwarf guards good enough to not be KOS. Wanted to try turning in CB belts to see if I could, was instantly struck down by an NPC in Kaladim, Bronlor Lightblade. I looked him up on the wiki to see what faction(s) he's on, to see if I could win him over, but it says no factions.

Is there any way I can complete this quest, or is this not doable as a necro?

I noticed there is a comment on the wiki page for the crushbone belts quest:
"As an iksar necro, my parser counted 600+ rep gains by killing orcs till I hit threatening with storm guard. 100ish more and you will be dubious and can do this quest."

so that implies to me that its possible. Do I just need to stay invis and be very careful about where I walk around or ... what?

Yeah, nevermind, just gotta stay invis until I get into Canloe's chamber. There's some dwarfs in the rooms along that hall that are KOS to necros no matter what faction you have.
