Ovim Wool Tunic of Casting

Taken all the way down to base materials, one Ovim Wool Tunic of Casting is 4 crafting steps deep and needs 9 intermediates — Grade 1 Intelligence Alkahest ×2, Ovim Wool ×2, Hardsilver Nugget ×1 and 6 others — which resolve to 14 distinct raw materials totalling 36 units, plus 74 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,629 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 13 of those crystals go into the final step; the other 61 are burned by the intermediates, so the real crystal cost is 21 Lightning Crystal, 21 Wind Crystal, 20 Water Crystal and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 76, Alchemist to Lv 76, Goldsmith to Lv 76 and Leatherworker to Lv 76 — so no single class can finish it unaided.

11 of the 14 raw materials come out of the ground, and one of them is time-gated: Ala Mhigan Salt Crystal (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Hardsilver Nugget has the widest use: 88 recipes call for it, spanning seven of the eight crafting classes.
