Plumed Bronze Pickaxe

Taken all the way down to base materials, one Plumed Bronze Pickaxe is 4 crafting steps deep and needs 6 intermediates — Bronze Pickaxe ×1, Hard Leather ×1, Bronze Ingot ×1 and 3 others — which resolve to 6 distinct raw materials totalling 10 units, plus 9 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 647 of the 1,932 Blacksmith ones, and 1 recipe nests deeper.

Only 2 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 3 Earth Shard, 3 Fire Shard, 2 Lightning Shard and 1 other kind.

The chain crosses four disciplines — Blacksmith to Lv 16, Leatherworker to Lv 8, Weaver to Lv 2 and Carpenter to Lv 1 — 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, Bronze Ingot has the widest use: 76 recipes call for it, spanning six of the eight crafting classes.
