Armor Hanger

Taken all the way down to base materials, one Armor Hanger is 2 crafting steps deep and needs 2 intermediates — Cut Stone ×2 and Dwarven Mythril Ingot ×2 — which resolve to 4 distinct raw materials totalling 17 units, plus 34 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 660 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 14 Fire Crystal, 7 Earth Crystal, 7 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 80, Blacksmith to Lv 78 and Goldsmith to Lv 30 — so no single class can finish it unaided.

3 of the 4 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
