Replica Allagan Blade ★★★

Taken all the way down to base materials, one Replica Allagan Blade is 2 crafting steps deep and needs 2 intermediates — Wootz Ingot ×3 and Platinum Ingot ×1 — which resolve to 6 distinct raw materials totalling 19 units, plus 21 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 804 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 11 Fire Cluster, 8 Earth Cluster and 2 Wind Cluster.

The chain crosses two disciplines — Blacksmith to Lv 60 and Goldsmith to Lv 50 — so no single class can finish it unaided.

1 of the 6 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.
