Horn Ring

Taken all the way down to base materials, one Horn Ring is 2 crafting steps deep and needs 1 intermediate — Siltstone Whetstone ×1 — which resolves to 2 distinct raw materials totalling 3 units, plus 9 crystals.

That bill outweighs 3,373 of the 13,602 recipes tracked here and 451 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 3 are burned by the intermediates, so the real crystal cost is 6 Wind Shard and 3 Fire Shard.

Every step is Goldsmith work, from a Lv 30 intermediate up to the Lv 31 finish, so one class covers the whole chain.

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.
