Steel Dolabra

Taken all the way down to base materials, one Steel Dolabra is 3 crafting steps deep and needs 6 intermediates — Steel Ingot ×3, Oak Lumber ×1, Steel Plate ×1 and 3 others — which resolve to 5 distinct raw materials totalling 16 units, plus 22 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 750 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 3 Earth Shard, 3 Ice Shard and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 33, Carpenter to Lv 32, Armorer to Lv 27 and Weaver to Lv 24 — so no single class can finish it unaided.

4 of the 5 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
