Dominus Shield ★★

Taken all the way down to base materials, one Dominus Shield is 2 crafting steps deep and needs 3 intermediates — Tungsten Steel Ingot ×2, Grade 2 Vitality Alkahest ×1 and Stonegold Nugget ×1 — which resolve to 7 distinct raw materials totalling 23 units, plus 22 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 847 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 6 Wind Crystal, 4 Fire Cluster and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 80, Alchemist to Lv 80, Blacksmith to Lv 80 and Goldsmith to Lv 71 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Tungsten Ore (10:00, 22:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Tungsten Steel Ingot has the widest use: 113 recipes call for it, spanning six of the eight crafting classes.
