Neo-Ishgardian Cap of Healing ★★★

Taken all the way down to base materials, one Neo-Ishgardian Cap of Healing is 2 crafting steps deep and needs 4 intermediates — Duskcourt Cloth ×2, Grade 3 Mind Alkahest ×2, Dwarven Mythril Nugget ×1 and 1 other — which resolve to 11 distinct raw materials totalling 30 units, plus 27 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,408 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 8 Lightning Cluster, 8 Wind Cluster, 7 Wind Crystal and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 80, Alchemist to Lv 80, Leatherworker to Lv 80 and Goldsmith to Lv 78 — so no single class can finish it unaided.

6 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Ashen Alumen (10:00, 22:00), Duskblooms (4:00, 16:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Dwarven Mythril Nugget has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
