Armorer's Visor ★

Taken all the way down to base materials, one Armorer's Visor is 3 crafting steps deep and needs 6 intermediates — Boar Leather ×1, Cobalt Plate ×1, Darksteel Plate ×1 and 3 others — which resolve to 7 distinct raw materials totalling 16 units, plus 36 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 6 Fire Crystal, 6 Ice Crystal and 3 other kinds.

The chain crosses three disciplines — Armorer to Lv 50, Blacksmith to Lv 50 and Leatherworker to Lv 50 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
