Best Man's Slacks ★★

Taken all the way down to base materials, one Best Man's Slacks is 3 crafting steps deep and needs 4 intermediates — Undyed Woolen Cloth ×2, Vanya Silk ×1, Woolen Yarn ×4 and 1 other — which resolve to 5 distinct raw materials totalling 20 units, plus 19 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,022 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 10 Lightning Shard, 6 Lightning Crystal, 2 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.
