Mounted Bookshelf

Taken all the way down to base materials, one Mounted Bookshelf is 2 crafting steps deep and needs 1 intermediate — Rosewood Lumber ×5 — which resolves to 3 distinct raw materials totalling 17 units, plus 41 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 692 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 36 Wind Shard and 5 Ice Shard.

Every step is Carpenter work, from a Lv 45 intermediate up to the Lv 45 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.

Mounted Bookshelf is itself consumed by 1 further recipe, all of them Carpenter recipes.
