Rarefied Ra'Kaznar Ring

Taken all the way down to base materials, one Rarefied Ra'Kaznar Ring is 3 crafting steps deep and needs 4 intermediates — Ra'Kaznar Ingot ×2, Black Star ×1, Thunderyards Silk ×1 and 1 other — which resolve to 4 distinct raw materials totalling 24 units, plus 56 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 881 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 16 Fire Crystal, 8 Earth Crystal, 8 Ice Crystal and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 100, Blacksmith to Lv 98, Goldsmith to Lv 98, Weaver to Lv 98 and Alchemist to Lv 95 — 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, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
