Spruce Pattens ★★

Taken all the way down to base materials, one Spruce Pattens is 3 crafting steps deep and needs 5 intermediates — Raptor Leather ×1, Treated Spruce Lumber ×1, Undyed Felt ×1 and 2 others — which resolve to 9 distinct raw materials totalling 23 units, plus 21 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 869 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 6 Wind Crystal, 5 Earth Shard, 5 Lightning Shard and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Weaver to Lv 43, Leatherworker to Lv 41 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 9 raw materials come out of the ground, and one of them is time-gated: Spruce Log (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Undyed Felt has the widest use: 107 recipes call for it, spanning six of the eight crafting classes.
