Projection Module ★★★

Taken all the way down to base materials, one Projection Module is 3 crafting steps deep and needs 4 intermediates — Rose Gold Nugget ×4, Cobalt Plate ×3, Gold Ingot ×2 and 1 other — which resolve to 7 distinct raw materials totalling 41 units, plus 66 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,267 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 63 are burned by the intermediates, so the real crystal cost is 30 Fire Shard, 15 Ice Shard, 12 Wind Crystal and 4 other kinds.

The chain crosses three disciplines — Armorer to Lv 50, Goldsmith to Lv 50 and Blacksmith to Lv 42 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Native Gold (4:00). The widest gap between consecutive opening times is 19 Eorzean hours, about 55 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
