Best Man's Jacket ★★

Taken all the way down to base materials, one Best Man's Jacket is 3 crafting steps deep and needs 4 intermediates — Vanya Silk ×2, Undyed Woolen Cloth ×1, Silk Thread ×5 and 1 other — which resolve to 5 distinct raw materials totalling 30 units, plus 18 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,408 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 9 Lightning Crystal, 5 Lightning Shard, 3 Lightning Cluster and 1 other kind.

Every step is Weaver work, from a Lv 38 intermediate up to the Lv 50 finish, so one class covers the whole chain.

2 of the 5 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.
