Book of Ra'Kaznar

Taken all the way down to base materials, one Book of Ra'Kaznar is 2 crafting steps deep and needs 4 intermediates — Claro Walnut Lumber ×2, Ra'Kaznar Ingot ×2, Sanctified Water ×1 and 1 other — which resolve to 9 distinct raw materials totalling 31 units, plus 64 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,379 of the 1,591 Alchemist ones, and 4,464 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 Water Crystal, 16 Fire Crystal, 16 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Alchemist to Lv 98, Blacksmith to Lv 98 and Carpenter to Lv 98 — so no single class can finish it unaided.

7 of the 9 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
