Spinnerbait

Taken all the way down to base materials, a batch of 3 Spinnerbait is 3 crafting steps deep and needs 3 intermediates — Cobalt Ingot ×1, Undyed Felt ×1 and Natron ×1 — which resolve to 6 distinct raw materials totalling 8 units, plus 23 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 742 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 10 Fire Shard, 6 Wind Shard, 5 Lightning Shard and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 47, Weaver to Lv 43, Blacksmith to Lv 42 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 6 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, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
