Wyvernskin Ring

Taken all the way down to base materials, one Wyvernskin Ring is 3 crafting steps deep and needs 3 intermediates — Mythrite Ingot ×1, Wyvern Leather ×1 and Mythrite Nugget ×1 — which resolve to 5 distinct raw materials totalling 14 units, plus 16 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 807 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 9 are burned by the intermediates, so the real crystal cost is 7 Earth Crystal, 6 Fire Crystal and 3 Wind Crystal.

The chain crosses two disciplines — Leatherworker to Lv 53 and Blacksmith to Lv 52 — so no single class can finish it unaided.

4 of the 5 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.
