Wyvernskin Grimoire

Taken all the way down to base materials, one Wyvernskin Grimoire is 3 crafting steps deep and needs 4 intermediates — Wyvern Leather ×2, Enchanted Mythrite Ink ×1, Mythrite Ingot ×1 and 1 other — which resolve to 6 distinct raw materials totalling 24 units, plus 21 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,315 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 6 Fire Crystal, 6 Water Crystal and 1 other kind.

The chain crosses three disciplines — Alchemist to Lv 52, Blacksmith to Lv 52 and Leatherworker to Lv 52 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
