Aurum Regis Circlet of Healing

Taken all the way down to base materials, one Aurum Regis Circlet of Healing is 3 crafting steps deep and needs 6 intermediates — Aurum Regis Nugget ×2, Chimerical Felt ×1, Grade 1 Mind Dissolvent ×1 and 3 others — which resolve to 12 distinct raw materials totalling 37 units, plus 33 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,852 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 19 Wind Crystal, 5 Lightning Crystal, 4 Water Crystal and 3 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 60, Weaver to Lv 58 and Alchemist to Lv 54 — so no single class can finish it unaided.

9 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
