Neo-Ishgardian Ring of Healing ★★★

Taken all the way down to base materials, one Neo-Ishgardian Ring of Healing is 2 crafting steps deep and needs 4 intermediates — Grade 3 Mind Alkahest ×1, Lignum Vitae Lumber ×1, Merbau Lumber ×1 and 1 other — which resolve to 10 distinct raw materials totalling 23 units, plus 23 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 869 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 7 Wind Crystal, 6 Wind Cluster, 4 Ice Cluster and 3 other kinds.

The chain crosses three disciplines — Carpenter to Lv 80, Alchemist to Lv 80 and Goldsmith to Lv 80 — so no single class can finish it unaided.

5 of the 10 raw materials come out of the ground, and 3 of them are time-gated: Imperial Fern (0:00, 12:00), Merbau Log (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
