Bluespirit Spear

Taken all the way down to base materials, one Bluespirit Spear is 3 crafting steps deep and needs 5 intermediates — Bluespirit Tile ×2, White Ash Lumber ×2, Darksteel Nugget ×1 and 2 others — which resolve to 6 distinct raw materials totalling 25 units, plus 53 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 963 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 25 Wind Crystal, 17 Fire Crystal, 6 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 74, Blacksmith to Lv 74 and Goldsmith to Lv 55 — so no single class can finish it unaided.

All 6 raw materials are gathered, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Darksteel Nugget has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
