Sheep Rug

Taken all the way down to base materials, one Sheep Rug is 2 crafting steps deep and needs 1 intermediate — Boar Leather ×5 — which resolves to 4 distinct raw materials totalling 16 units, plus 29 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 847 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 25 Earth Shard and 4 Wind Shard.

Every step is Leatherworker work, from a Lv 33 intermediate up to the Lv 40 finish, so one class covers the whole chain.

1 of the 4 raw materials matches a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Boar Leather has the widest use: 117 recipes call for it, spanning six of the eight crafting classes.
