Black Star Earrings of Crafting

Taken all the way down to base materials, one Black Star Earrings of Crafting is 3 crafting steps deep and needs 3 intermediates — Black Star ×2, Ra'Kaznar Ingot ×1 and Magnesia Whetstone ×2 — which resolve to 3 distinct raw materials totalling 20 units, plus 56 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,141 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 24 Wind Crystal, 16 Fire Crystal and 16 Water Crystal.

The chain crosses three disciplines — Goldsmith to Lv 100, Blacksmith to Lv 98 and Alchemist to Lv 95 — so no single class can finish it unaided.

All 3 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, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
