Warning, this mission will disappear if you don't go on it quickly enough. I wanted to wait until I was 100% chance of completion leveling up one last follower with the needed trait, but after about 2.5 days, the mission was no longer offered to me. I should have tried it while I had the chance.
Just like with the equal mission Drov the Ruiner, the
does not count towards the weekly 3, Meaning if you get either in a week, you'll have 4, if you spend any of the other currencies on the others.
Upon successful completion the
simply disappears when you have 10 already.
Would be nice if instead you would get a chance to either resources or gold :-)
