artifact materials?

  • artifact materials?

    I was running through a dungeon today with a large group of people. I got a lot of silver and fame but not much in the way of runes and souls. I'm currently grinding for T4 leather stalker and hellion armor but whenever I helped kill something that dropped that item, I couldn't gather it on most occasions. Is there a mechanic I should know about, or any tips for getting these materials? thanks!
