Rarefied Claro Walnut Flat Brush

Taken all the way down to base materials, one Rarefied Claro Walnut Flat Brush is 2 crafting steps deep and needs 3 intermediates — Claro Walnut Lumber ×2, Thunderyards Silk ×1 and Tungsten Ink ×1 — which resolve to 6 distinct raw materials totalling 20 units, plus 48 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,279 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 16 Lightning Crystal, 16 Water Crystal and 16 Wind Crystal.

The chain crosses three disciplines — Alchemist to Lv 100, Carpenter to Lv 98 and Weaver to Lv 98 — so no single class can finish it unaided.

5 of the 6 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Thunderyards Silk has the widest use: 120 recipes call for it, spanning seven of the eight crafting classes.
