Replica High Allagan Mask of Casting ★★

Taken all the way down to base materials, one Replica High Allagan Mask of Casting is 2 crafting steps deep and needs 3 intermediates — Arachne Velveteen ×2, Kirimu Leather ×1 and Platinum Ingot ×1 — which resolve to 8 distinct raw materials totalling 22 units, plus 20 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 10 Wind Cluster, 4 Earth Cluster, 4 Lightning Cluster and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 60, Goldsmith to Lv 50 and Weaver to Lv 50 — so no single class can finish it unaided.

1 of the 8 raw materials come out of the ground, and one of them is time-gated: Platinum Ore (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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