Glacial Coat ★

Taken all the way down to base materials, one Glacial Coat is 2 crafting steps deep and needs 2 intermediates — Silk Thread ×2 and Boar Leather ×1 — which resolve to 5 distinct raw materials totalling 7 units, plus 12 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 598 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 4 Earth Shard, 3 Earth Crystal, 3 Lightning Crystal and 1 other kind.

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

3 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.
