Fortemps Manor Interior Wall ★★

Taken all the way down to base materials, one Fortemps Manor Interior Wall is 4 crafting steps deep and needs 11 intermediates — Hallowed Ramie Cloth ×6, Mortar ×4, Sewing Thread ×4 and 8 others — which resolve to 15 distinct raw materials totalling 96 units, plus 160 crystals.

That bill outweighs 13,461 of the 13,602 recipes tracked here and 1,959 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 156 are burned by the intermediates, so the real crystal cost is 87 Lightning Crystal, 28 Wind Crystal, 20 Water Crystal and 5 other kinds.

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

12 of the 15 raw materials come out of the ground, and 4 of them are time-gated: Abalathian Mistletoe (6:00, 18:00), Astral Moraine (0:00, 12:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Crawler Silk has the widest use: 178 recipes call for it, spanning five of the eight crafting classes.
