Toadskin Workboots

Taken all the way down to base materials, one Toadskin Workboots is 3 crafting steps deep and needs 5 intermediates — Toad Leather ×2, Rubber ×1, Undyed Velveteen ×1 and 2 others — which resolve to 6 distinct raw materials totalling 10 units, plus 14 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 691 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 7 Earth Shard, 3 Lightning Shard, 3 Wind Shard and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 31, Weaver to Lv 24 and Alchemist to Lv 7 — so no single class can finish it unaided.

3 of the 6 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
