Horse Chestnut Necklace of Gathering

Taken all the way down to base materials, one Horse Chestnut Necklace of Gathering is 2 crafting steps deep and needs 2 intermediates — Horse Chestnut Lumber ×3 and Dark Hempen Cloth ×1 — which resolve to 2 distinct raw materials totalling 20 units, plus 47 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 15 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 32 Wind Crystal, 8 Lightning Crystal and 7 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 81 and Weaver to Lv 81 — 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, Dark Hempen Cloth has the widest use: 55 recipes call for it, spanning six of the eight crafting classes.
