Opal Ring of Fending

Taken all the way down to base materials, one Opal Ring of Fending is 3 crafting steps deep and needs 5 intermediates — Grade 1 Vitality Dissolvent ×1, Hardsilver Ingot ×1, Opal ×1 and 2 others — which resolve to 8 distinct raw materials totalling 23 units, plus 32 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 1,288 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 4 Fire Crystal and 4 Water Crystal.

The chain crosses two disciplines — Goldsmith to Lv 56 and Alchemist to Lv 54 — so no single class can finish it unaided.

6 of the 8 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
