Ruthenium Tuck

Taken all the way down to base materials, one Ruthenium Tuck is 3 crafting steps deep and needs 4 intermediates — Ruthenium Ingot ×3, Ihuykanite ×1, Lar Ingot ×1 and 1 other — which resolve to 6 distinct raw materials totalling 35 units, plus 71 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,790 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal and 31 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 6 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, Lar Ingot has the widest use: 101 recipes call for it, spanning six of the eight crafting classes.
