The Lord of the Rings: Return to Moria

Durin's Armor can only be crafted using Durin's Forge, located in Desolation.
After repairing the Forge, you'll gain access to crafting Durinul Ingots, which can be crafted using a Salt Bath in your base.
Durinul Ingots call for 3 Gundabag Slag (drops from enemies, particularly Uruks) and 3 Salt.

The full set of Durin Armor is:
Durin's Helmet - 2 Star-metal ingots, 2 Durinul Iron Ingots, 3 Sun-stone, 1 Fine Leather
Durin's Armor - 3 Star-metal ingots, 2 Durinul Iron Ingots, 3 Sun-stone, 3 Fine Leather, 4 Fine Cloth
Durin's Gloves - 3 Star-metal ingots, 2 Durinul Iron Ingots, 3 Sun-stone, 2 Fine Leather

For a total of: 14 Star-metal ingots, 10 Durinul Iron Ingots, 15 Sun-stone, 7 Fine Leather, 7 Fine Cloth, 6 Ironwood

***NOTE: Some armor sets have variants with the new update. The above is for the base set - the variants are NOT required for "craft all" achievements, and might not count for "craft all" achievements if made instead of the base set.

I created a spreadsheet for all of your crafting needs relating to these achievements, you can find it here:
