Diadochos Bottoms of Casting ★★★★

Taken all the way down to base materials, one Diadochos Bottoms of Casting is 2 crafting steps deep and needs 4 intermediates — Garnet Cotton ×3, Deinosuchus Leather ×2, Grade 8 Intelligence Alkahest ×2 and 1 other — which resolve to 9 distinct raw materials totalling 46 units, plus 50 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,838 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 18 Wind Cluster, 15 Lightning Cluster, 8 Lightning Crystal and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 90, Alchemist to Lv 90 and Leatherworker to Lv 90 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Field Mustard (10:00, 22:00), Lovingbloom (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, AR-Caean Velvet has the widest use: 136 recipes call for it, spanning six of the eight crafting classes.
