Indagator's Ring of Gathering ★★★

Taken all the way down to base materials, one Indagator's Ring of Gathering is 2 crafting steps deep and needs 3 intermediates — Titanoboa Leather ×2, Zoisite ×2 and Paldao Lumber ×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 1,670 of the 1,844 Leatherworker 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 20 Wind Cluster, 11 Earth Cluster, 6 Fire Cluster and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 90, Carpenter 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: Haritaki (0:00, 12:00), 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, Titanoboa Leather has the widest use: 55 recipes call for it, spanning six of the eight crafting classes.
