Paladin's Arms of the Round ★★★

Taken all the way down to base materials, one Paladin's Arms of the Round is 3 crafting steps deep and needs 5 intermediates — High Mythrite Ingot ×3, Luminous Fiber ×3, Platinum Ingot ×3 and 2 others — which resolve to 13 distinct raw materials totalling 71 units, plus 45 crystals.

That bill outweighs 13,309 of the 13,602 recipes tracked here and 1,406 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 15 Fire Cluster, 11 Earth Cluster, 8 Wind Cluster and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 60, Alchemist to Lv 60, Blacksmith to Lv 60, Leatherworker to Lv 60 and Goldsmith to Lv 50 — so no single class can finish it unaided.

7 of the 13 raw materials come out of the ground, and 5 of them are time-gated: Crystallized Sap (8:00, 20:00), Lumythrite Ore (2:00, 14:00) and 3 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
