Neo-Ishgardian Cap of Maiming ★★★

Taken all the way down to base materials, one Neo-Ishgardian Cap of Maiming is 2 crafting steps deep and needs 4 intermediates — Duskcourt Cloth ×2, Grade 3 Strength Alkahest ×2, Dwarven Mythril Ingot ×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 Fire Crystal and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 80, Alchemist to Lv 80, Goldsmith to Lv 80 and Blacksmith 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: Duskblooms (4:00, 16:00), Imperial Fern (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
