Ironwood Necklace of Crafting

Taken all the way down to base materials, one Ironwood Necklace of Crafting is 3 crafting steps deep and needs 4 intermediates — Ametrine ×1, Ironwood Lumber ×1, Scarlet Moko Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totalling 17 units, plus 48 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 692 of the 1,552 Carpenter ones, and 337 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 32 Wind Crystal, 8 Ice Crystal and 8 Lightning Crystal.

The chain crosses three disciplines — Carpenter to Lv 86, Weaver to Lv 86 and Goldsmith to Lv 81 — 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, Ametrine has the widest use: 85 recipes call for it, spanning six of the eight crafting classes.
