Hingan Bookshelf

Taken all the way down to base materials, one Hingan Bookshelf is 3 crafting steps deep and needs 6 intermediates — Beech Lumber ×6, Steel Joint Plate ×4, Varnish ×3 and 3 others — which resolve to 7 distinct raw materials totalling 61 units, plus 73 crystals.

That bill outweighs 13,148 of the 13,602 recipes tracked here and 1,425 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 68 are burned by the intermediates, so the real crystal cost is 27 Wind Crystal, 24 Water Shard, 12 Ice Shard and 2 other kinds.

The chain crosses four disciplines — Carpenter to Lv 61, Alchemist to Lv 41, Armorer to Lv 27 and Blacksmith to Lv 26 — so no single class can finish it unaided.

6 of the 7 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
