Sylphic Bookshelf

Taken all the way down to base materials, one Sylphic Bookshelf is 2 crafting steps deep and needs 2 intermediates — Mahogany Lumber ×6 and Electrum Ingot ×4 — which resolve to 3 distinct raw materials totalling 36 units, plus 60 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,827 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 50 are burned by the intermediates, so the real crystal cost is 55 Wind Shard and 5 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 43 and Carpenter to Lv 39 — so no single class can finish it unaided.

2 of the 3 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, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
