Indagator's Ring of Crafting ★★★

Taken all the way down to base materials, one Indagator's Ring of Crafting is 2 crafting steps deep and needs 3 intermediates — Paldao Lumber ×2, Zoisite ×2 and Ilmenite Ingot ×1 — which resolve to 8 distinct raw materials totalling 35 units, plus 40 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,171 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 17 Wind Cluster, 11 Ice Cluster, 9 Fire Cluster and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 90, Blacksmith to Lv 90 and Goldsmith to Lv 90 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Ilmenite (8:00, 20:00), Paldao Log (2:00, 14:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Ilmenite Ingot has the widest use: 73 recipes call for it, spanning six of the eight crafting classes.
