Shadow of war - lost Gondorian artifacts

There are a number of lost Gondorian artifacts within the shadow of Mordor realm. In this video I will show to obtain each one in each man area- Minas Ithil, Cirith Ungul, Nurnen, Seregost, and Gorgoroth, which once all completed unlocks the prospector ability. This allows you to receive higher quality gems from enemies.
I have marked the time for each main area on the video.
Minas ithil- 02:00
Cirith Ungul- 07:28
Gondor- 13:52
Seregost- 20:48
Gorgoroth- 29:14
I hope this helps with obtaining all the artifacts, especially those completionists out there.
