Cauldronmaster's Longkilt ★★

Taken all the way down to base materials, one Cauldronmaster's Longkilt is 3 crafting steps deep and needs 5 intermediates — Astral Silk ×4, Aurum Regis Nugget ×1, Iolite ×1 and 2 others — which resolve to 13 distinct raw materials totalling 48 units, plus 38 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,860 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 15 Lightning Crystal, 8 Wind Cluster, 7 Lightning Cluster and 3 other kinds.

The chain crosses three disciplines — Weaver to Lv 60, Alchemist to Lv 60 and Goldsmith to Lv 58 — so no single class can finish it unaided.

7 of the 13 raw materials come out of the ground, and 5 of them are time-gated: Astral Moraine (0:00, 12:00), Seventh Heaven (4:00, 16:00) and 3 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
