Phrygian Needle

Taken all the way down to base materials, one Phrygian Needle is 2 crafting steps deep and needs 3 intermediates — Phrygian Gold Ingot ×2, Bismuth Ingot ×1 and Chloroschist Whetstone ×1 — which resolve to 5 distinct raw materials totalling 22 units, plus 47 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,234 of the 2,216 Goldsmith 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 and 15 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 85 and Blacksmith to Lv 84 — so no single class can finish it unaided.

All 5 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, Bismuth Ingot has the widest use: 104 recipes call for it, spanning six of the eight crafting classes.
