Oak Pattens

Taken all the way down to base materials, one Oak Pattens is 3 crafting steps deep and needs 4 intermediates — Boar Leather ×1, Oak Lumber ×1, Undyed Woolen Cloth ×1 and 1 other — which resolve to 4 distinct raw materials totaling 7 units, plus 21 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 509 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 8 Wind Shard, 5 Lightning Shard, 4 Earth Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 39, Weaver to Lv 39 and Leatherworker to Lv 33 — so no single class can finish it unaided.

2 of the 4 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, Undyed Woolen Cloth has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
