Rarefied Ruthenium War Axe

Taken all the way down to base materials, one Rarefied Ruthenium War Axe is 2 crafting steps deep and needs 3 intermediates — Ruthenium Ingot ×2, Ceiba Lumber ×1 and Mountain Linen ×1 — which resolve to 4 distinct raw materials totalling 22 units, plus 47 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 917 of the 1,932 Blacksmith 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 24 Fire Crystal, 8 Lightning Crystal, 8 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 93, Carpenter to Lv 92 and Weaver 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, Ruthenium Ingot has the widest use: 82 recipes call for it, spanning six of the eight crafting classes.
