High Durium Uchigatana

Taken all the way down to base materials, one High Durium Uchigatana is 2 crafting steps deep and needs 4 intermediates — High Durium Ingot ×3, Almasty Serge ×1, Chloroschist Whetstone ×1 and 1 other — which resolve to 6 distinct raw materials totalling 32 units, plus 63 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,223 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 16 Wind Crystal, 8 Lightning Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 82, Goldsmith to Lv 82 and Weaver to Lv 82 — 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, Almasty Serge has the widest use: 71 recipes call for it, spanning six of the eight crafting classes.
