Militia Spinning Wheel ★

Taken all the way down to base materials, one Militia Spinning Wheel is 3 crafting steps deep and needs 3 intermediates — Cobalt Rivets ×2, Spruce Lumber ×2 and Cobalt Ingot ×2 — which resolve to 3 distinct raw materials totalling 12 units, plus 31 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 602 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 20 Fire Shard, 9 Wind Crystal and 2 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 50 and Blacksmith to Lv 43 — so no single class can finish it unaided.

All 3 raw materials are gathered, 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
