Holy Rainbow Shoes

Taken all the way down to base materials, one Holy Rainbow Shoes is 4 crafting steps deep and needs 7 intermediates — Holy Rainbow Cloth ×2, Mythrite Nugget ×1, Rubber ×1 and 4 others — which resolve to 8 distinct raw materials totalling 32 units, plus 31 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,516 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 7 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 17 Lightning Crystal, 6 Water Crystal, 3 Fire Crystal and 3 other kinds.

The chain crosses three disciplines — Weaver to Lv 54, Alchemist to Lv 52 and Blacksmith to Lv 51 — so no single class can finish it unaided.

7 of the 8 raw materials come out of the ground, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
