Skybuilders' Waterproof Sheet

Taken all the way down to base materials, one Skybuilders' Waterproof Sheet is 2 crafting steps deep and needs 1 intermediate — Atrociraptor Leather ×1 — which resolves to 5 distinct raw materials totalling 29 units, plus 13 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,376 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 7 Earth Crystal, 4 Lightning Crystal and 2 Wind Crystal.

The chain crosses two disciplines — Weaver to Lv 80 and Leatherworker to Lv 74 — so no single class can finish it unaided.

4 of the 5 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, Atrociraptor Leather has the widest use: 70 recipes call for it, spanning five of the eight crafting classes.
