Scintillant Circlet of Striking ★★★★

Taken all the way down to base materials, one Scintillant Circlet of Striking is 3 crafting steps deep and needs 6 intermediates — Grade 3 Strength Dissolvent ×2, Iolite ×2, Scintillant Ingot ×2 and 3 others — which resolve to 16 distinct raw materials totalling 53 units, plus 47 crystals.

That bill outweighs 12,925 of the 13,602 recipes tracked here and 2,088 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 22 Wind Cluster, 16 Fire Cluster, 6 Lightning Cluster and 1 other kind.

The chain crosses three disciplines — Goldsmith to Lv 60, Alchemist to Lv 60 and Weaver to Lv 60 — so no single class can finish it unaided.

8 of the 16 raw materials come out of the ground, and 8 of them are time-gated: Luminium Ore (6:00, 18:00), Morel (4:00, 16:00) and 6 others. The widest gap between consecutive opening times is 7 Eorzean hours, about 20 real-world minutes.

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