Oddly Specific Gagana Leather ★★★

Taken all the way down to base materials, one Oddly Specific Gagana Leather is 2 crafting steps deep and needs 1 intermediate — Sea Swallow Leather ×1 — which resolves to 3 distinct raw materials totalling 6 units, plus 21 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 14 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 14 Earth Crystal and 7 Wind Crystal.

Every step is Leatherworker work, from a Lv 78 intermediate up to the Lv 80 finish, so one class covers the whole chain.

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

Of the intermediates, Sea Swallow Leather has the widest use: 124 recipes call for it, spanning six of the eight crafting classes.
