Rarefied Ra'Kaznar War Scythe

Taken all the way down to base materials, one Rarefied Ra'Kaznar War Scythe is 3 crafting steps deep and needs 3 intermediates — Black Star ×2, Ra'Kaznar Ingot ×2 and Magnesia Whetstone ×2 — which resolve to 3 distinct raw materials totalling 26 units, plus 64 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 1,087 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 16 Water Crystal, 16 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 99, Goldsmith 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.
