Replica Allagan Grimoire of Casting ★★★

Taken all the way down to base materials, one Replica Allagan Grimoire of Casting is 2 crafting steps deep and needs 4 intermediates — Ebony Lumber ×2, Kirimu Leather ×2, Platinum Ingot ×2 and 1 other — which resolve to 11 distinct raw materials totalling 59 units, plus 34 crystals.

That bill outweighs 13,079 of the 13,602 recipes tracked here and 1,551 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster, 5 Water Crystal, 4 Earth Cluster and 4 other kinds.

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

4 of the 11 raw materials come out of the ground, and 2 of them are time-gated: Ebony Log (4:00) and 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.
