Ra'Kaznar Ring of Gathering

Taken all the way down to base materials, one Ra'Kaznar Ring of Gathering is 2 crafting steps deep and needs 2 intermediates — Ra'Kaznar Ingot ×1 and Thunderyards Silk ×1 — which resolve to 3 distinct raw materials totalling 11 units, plus 32 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 555 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 8 Earth Crystal, 8 Fire Crystal, 8 Ice Crystal and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 100, Blacksmith to Lv 98 and Weaver to Lv 98 — 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.
