Marid Leather Boots of Healing

Taken all the way down to base materials, one Marid Leather Boots of Healing is 3 crafting steps deep and needs 7 intermediates — Marid Leather ×2, Durium Ingot ×1, Grade 1 Reisui of Mind ×1 and 4 others — which resolve to 13 distinct raw materials totalling 32 units, plus 42 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,613 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 19 Earth Crystal, 13 Wind Crystal, 9 Water Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 66, Alchemist to Lv 66 and Goldsmith to Lv 66 — so no single class can finish it unaided.

11 of the 13 raw materials match a gathering node, none of them timed; the other 2 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.
