Dragonskin Bottoms

Taken all the way down to base materials, one Dragonskin Bottoms is 3 crafting steps deep and needs 5 intermediates — Dragon Leather ×2, Cobalt Ingot ×1, Ramie Cloth ×1 and 2 others — which resolve to 6 distinct raw materials totalling 23 units, plus 32 crystals.

That bill outweighs 8,647 of the 13,602 recipes tracked here and 1,208 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 15 Earth Crystal, 6 Lightning Crystal, 5 Fire Shard and 2 other kinds.

The chain crosses three disciplines — Leatherworker to Lv 56, Weaver to Lv 54 and Blacksmith to Lv 42 — so no single class can finish it unaided.

5 of the 6 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
