Wall Lantern

Taken all the way down to base materials, one Wall Lantern is 2 crafting steps deep and needs 1 intermediate — Cobalt Ingot ×4 — which resolves to 4 distinct raw materials totalling 18 units, plus 32 crystals.

That bill outweighs 7,380 of the 13,602 recipes tracked here and 781 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 26 Fire Shard and 6 Earth Shard.

Every step is Blacksmith work, from a Lv 42 intermediate up to the Lv 50 finish, so one class covers the whole chain.

2 of the 4 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.
