Toadskin Jerkin

Taken all the way down to base materials, one Toadskin Jerkin is 3 crafting steps deep and needs 4 intermediates — Toad Leather ×3, Iron Ingot ×1, Undyed Cotton Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totalling 11 units, plus 15 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 724 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 9 are burned by the intermediates, so the real crystal cost is 9 Earth Shard, 3 Wind Shard, 2 Lightning Shard and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 30, Blacksmith to Lv 16 and Weaver to Lv 13 — so no single class can finish it unaided.

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

Of the intermediates, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
