Goblin Scimitar

Taken all the way down to base materials, one Goblin Scimitar is 2 crafting steps deep and needs 1 intermediate — Siltstone Whetstone ×1 — which resolves to 2 distinct raw materials totalling 3 units, plus 4 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 410 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 1 of those crystals go into the final step; the other 3 are burned by the intermediates, so the real crystal cost is 3 Wind Shard and 1 Fire Crystal.

The chain crosses two disciplines — Blacksmith to Lv 42 and Goldsmith to Lv 30 — so no single class can finish it unaided.

1 of the 2 raw materials matches a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Siltstone Whetstone has the widest use: 20 recipes call for it, spanning four of the eight crafting classes.
