Endless Expanse Rapier ★★

Taken all the way down to base materials, one Endless Expanse Rapier is 2 crafting steps deep and needs 3 intermediates — Eikon Iron Ingot ×2, High Mythrite Ingot ×2 and Treated Camphorwood Lumber ×1 — which resolve to 11 distinct raw materials totalling 43 units, plus 29 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,953 of the 2,216 Goldsmith 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 Wind Cluster, 10 Fire Cluster, 4 Earth Cluster and 2 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 60, Blacksmith to Lv 60 and Carpenter 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.
