Nana Bear ★★★★

Taken all the way down to base materials, one Nana Bear is 3 crafting steps deep and needs 3 intermediates — Cashmere Cloth ×1, Silk Thread ×1 and Diluted Vitriol ×1 — which resolve to 7 distinct raw materials totalling 23 units, plus 106 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 1,141 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 99 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 99 Lightning Shard, 3 Lightning Crystal, 2 Lightning Cluster and 2 other kinds.

The chain crosses two disciplines — Weaver to Lv 50 and Alchemist to Lv 50 — so no single class can finish it unaided.

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

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
