Rarefied Ihuykanite Circlet

Taken all the way down to base materials, one Rarefied Ihuykanite Circlet is 3 crafting steps deep and needs 3 intermediates — Ihuykanite ×2, Ruthenium Ingot ×2 and Annite Whetstone ×2 — which resolve to 4 distinct raw materials totalling 26 units, plus 63 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,562 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal and 23 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 93 and Blacksmith to Lv 92 — 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, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
