Horn Necklace

Taken all the way down to base materials, one Horn Necklace is 2 crafting steps deep and needs 1 intermediate — Dew Thread ×1 — which resolves to 2 distinct raw materials totalling 4 units, plus 5 crystals.

That bill outweighs 3,935 of the 13,602 recipes tracked here and 504 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 1 are burned by the intermediates, so the real crystal cost is 2 Fire Shard, 2 Wind Shard and 1 Lightning Shard.

The chain crosses two disciplines — Goldsmith to Lv 26 and Weaver to Lv 23 — so no single class can finish it unaided.

None of the 2 raw materials do not appear in the gathering data, so the whole bill comes from vendors, drops or content this site does not track.

Of the intermediates, Dew Thread has the widest use: 47 recipes call for it, spanning five of the eight crafting classes.
