Hemiskin Grimoire ★★★★

Taken all the way down to base materials, one Hemiskin Grimoire is 3 crafting steps deep and needs 6 intermediates — Hemicyon Leather ×3, Enchanted Platinum Ink ×2, Scintillant Ingot ×2 and 3 others — which resolve to 14 distinct raw materials totalling 76 units, plus 69 crystals.

That bill outweighs 13,379 of the 13,602 recipes tracked here and 1,566 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 63 are burned by the intermediates, so the real crystal cost is 21 Wind Cluster, 15 Water Cluster, 13 Lightning Cluster and 2 other kinds.

The chain crosses three disciplines — Alchemist to Lv 60, Goldsmith to Lv 60 and Leatherworker to Lv 60 — so no single class can finish it unaided.

5 of the 14 raw materials come out of the ground, and 4 of them are time-gated: Luminium Ore (6:00, 18:00), Wattle Bark (2:00, 14:00) and 2 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
