Rarefied Twinsilk Apron

Taken all the way down to base materials, one Rarefied Twinsilk Apron is 3 crafting steps deep and needs 3 intermediates — Twinsilk ×2, Palladium Nugget ×1 and Twinthread ×7 — which resolve to 4 distinct raw materials totalling 20 units, plus 28 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,022 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 18 Lightning Crystal and 10 Wind Crystal.

The chain crosses two disciplines — Weaver to Lv 70 and Goldsmith to Lv 68 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
