Morbol Bookshelf

Taken all the way down to base materials, one Morbol Bookshelf is 3 crafting steps deep and needs 4 intermediates — Hippogryph Leather ×4, Rosewood Lumber ×2, Undyed Woolen Cloth ×1 and 1 other — which resolve to 7 distinct raw materials totalling 20 units, plus 41 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,025 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 18 Wind Shard, 12 Earth Crystal, 6 Earth Shard and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 50, Carpenter to Lv 45 and Weaver to Lv 39 — so no single class can finish it unaided.

2 of the 7 raw materials match a gathering node, none of them timed; the other 5 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.
