Toadskin Jacket

Taken all the way down to base materials, one Toadskin Jacket is 2 crafting steps deep and needs 2 intermediates — Toad Leather ×2 and Aldgoat Leather ×1 — which resolve to 4 distinct raw materials totalling 7 units, plus 11 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 598 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 8 Earth Shard and 3 Wind Shard.

Every step is Leatherworker work, from a Lv 17 intermediate up to the Lv 30 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, Aldgoat Leather has the widest use: 98 recipes call for it, spanning seven of the eight crafting classes.
