Skyshrine & Cobalt Scar Exit

[Man0warr]

Yes for sure on him dropping it, not 100% sure it being a group gate at launch however I never had the key on my druid but was clicked through around a month into Velious to get CS portal fang.

you can do the quest for the key while KOS in about 20 minutes without killing anything. I mean, surely someone is going to kill the guy making the quest annoying, but the quest is quick. You just need someone to calm the noble who will aggro in kael.

Not so much - you can charm the noble in Kael to do turn ins but I'm pretty sure you need better than indifferent with Ziglark to do the turn in with for the key, so charming him won't work (maybe with Puppet Strings?).
