Peteinosaur Leather ★★★

Taken all the way down to base materials, one Peteinosaur Leather is 2 crafting steps deep and needs 1 intermediate — Camphor ×1 — which resolves to 2 distinct raw materials totalling 6 units, plus 9 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 5 of those crystals go into the final step; the other 4 are burned by the intermediates, so the real crystal cost is 3 Earth Cluster, 2 Lightning Cluster, 2 Water Cluster and 1 other kind.

The chain crosses two disciplines — Leatherworker to Lv 60 and Alchemist to Lv 60 — so no single class can finish it unaided.

1 of the 2 raw materials matches a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Peteinosaur Leather is itself consumed by 28 further recipes, spanning three of the eight crafting classes.
