Holy Cedar Armillae

Taken all the way down to base materials, one Holy Cedar Armillae is 3 crafting steps deep and needs 5 intermediates — Holy Cedar Lumber ×2, Varnish ×1, Holy Water ×4 and 2 others — which resolve to 6 distinct raw materials totalling 23 units, plus 33 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 869 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 16 Wind Crystal, 8 Water Shard, 6 Water Crystal and 1 other kind.

The chain crosses two disciplines — Carpenter to Lv 53 and Alchemist to Lv 52 — so no single class can finish it unaided.

5 of the 6 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, Varnish has the widest use: 114 recipes call for it, spanning four of the eight crafting classes.
