Iridescent Acton of Aiming

Taken all the way down to base materials, one Iridescent Acton of Aiming is 3 crafting steps deep and needs 5 intermediates — Green Glider Leather ×2, Iridescent Silk ×2, Electrum Ingot ×1 and 2 others — which resolve to 6 distinct raw materials totalling 27 units, plus 44 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,307 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 21 Lightning Crystal, 12 Earth Crystal, 6 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Weaver to Lv 73, Leatherworker to Lv 72 and Goldsmith to Lv 42 — so no single class can finish it unaided.

5 of the 6 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
