Altered Thighboots

Taken all the way down to base materials, one Altered Thighboots is 2 crafting steps deep and needs 3 intermediates — Bronze Ingot ×1, Leather ×1 and Rubber ×1 — which resolve to 5 distinct raw materials totalling 6 units, plus 5 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 537 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

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

The chain crosses three disciplines — Leatherworker to Lv 5, Alchemist to Lv 7 and Blacksmith to Lv 1 — so no single class can finish it unaided.

One intermediate outranks the result: Rubber is a Lv 7 Alchemist recipe feeding a Lv 5 craft, so that step, not the last one, is the real gate.

3 of the 5 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.
