Hardsilver Rapier

Taken all the way down to base materials, one Hardsilver Rapier is 3 crafting steps deep and needs 5 intermediates — Hardsilver Nugget ×2, Titanium Nugget ×2, Holy Cedar Lumber ×1 and 2 others — which resolve to 8 distinct raw materials totalling 35 units, plus 32 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,790 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 25 are burned by the intermediates, so the real crystal cost is 18 Wind Crystal, 11 Fire Crystal and 3 Water Crystal.

The chain crosses four disciplines — Goldsmith to Lv 54, Blacksmith to Lv 54, Alchemist to Lv 52 and Carpenter to Lv 52 — so no single class can finish it unaided.

All 8 raw materials are gathered, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
