Hardsilver Needle

Taken all the way down to base materials, one Hardsilver Needle is 3 crafting steps deep and needs 5 intermediates — Hardsilver Nugget ×2, Basilisk Whetstone ×1, Holy Cedar Lumber ×1 and 2 others — which resolve to 6 distinct raw materials totalling 22 units, plus 29 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,234 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 18 Wind Crystal, 5 Wind Shard, 3 Fire Crystal and 1 other kind.

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

All 6 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, Hardsilver Nugget has the widest use: 88 recipes call for it, spanning seven of the eight crafting classes.
