High Steel Knuckles

Taken all the way down to base materials, one High Steel Knuckles is 3 crafting steps deep and needs 6 intermediates — High Steel Nugget ×2, Spinel ×2, Beech Lumber ×1 and 3 others — which resolve to 9 distinct raw materials totalling 29 units, plus 34 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,176 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 10 Wind Shard, 9 Fire Crystal, 6 Wind Crystal and 3 other kinds.

The chain crosses five disciplines — Blacksmith to Lv 61, Carpenter to Lv 61, Goldsmith to Lv 61, Weaver to Lv 58 and Alchemist to Lv 25 — 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
