Rarefied Integral Armillae

Taken all the way down to base materials, one Rarefied Integral Armillae is 2 crafting steps deep and needs 2 intermediates — AR-Caean Velvet ×2 and Integral Lumber ×2 — which resolve to 2 distinct raw materials totalling 20 units, plus 48 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 791 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 16 Lightning Crystal and 8 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 89 and Weaver to Lv 88 — so no single class can finish it unaided.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

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