Leather Boots

Taken all the way down to base materials, one Leather Boots is 3 crafting steps deep and needs 4 intermediates — Leather ×1, Rubber ×1, Undyed Hempen Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totalling 5 units, plus 6 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 489 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 2 Earth Shard, 2 Lightning Shard, 1 Water Shard and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 6, Alchemist to Lv 7 and Weaver to Lv 2 — so no single class can finish it unaided.

One intermediate outranks the result: Rubber is a Lv 7 Alchemist recipe feeding a Lv 6 craft, so that step, not the last one, is the real gate.

2 of the 4 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.
