Crimson Coral Object ★★

Taken all the way down to base materials, one Crimson Coral Object is 3 crafting steps deep and needs 2 intermediates — Chromite Ingot ×2 and Molybdenum Ingot ×2 — which resolve to 6 distinct raw materials totalling 27 units, plus 22 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,605 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 6 Fire Cluster, 4 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Goldsmith to Lv 70 and Blacksmith to Lv 70 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Chromite Ore (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Chromite Ingot has the widest use: 121 recipes call for it, spanning six of the eight crafting classes.
