Paladin's Endless Expanse Arms ★★

Taken all the way down to base materials, one Paladin's Endless Expanse Arms is 2 crafting steps deep and needs 3 intermediates — High Mythrite Ingot ×3, Eikon Iron Ingot ×1 and Treated Camphorwood Lumber ×1 — which resolve to 11 distinct raw materials totalling 42 units, plus 29 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,501 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 11 Fire Cluster, 8 Wind Cluster, 6 Earth Cluster and 2 other kinds.

The chain crosses three disciplines — Blacksmith to Lv 60, Carpenter to Lv 60 and Goldsmith to Lv 60 — so no single class can finish it unaided.

5 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Lumythrite Ore (2:00, 14:00), Old-growth Camphorwood Log (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
