Ahriman Bookshelf

Taken all the way down to base materials, one Ahriman Bookshelf is 3 crafting steps deep and needs 3 intermediates — Steel Ingot ×5, Walnut Lumber ×3 and Steel Rivets ×2 — which resolve to 4 distinct raw materials totalling 25 units, plus 29 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,056 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 20 Fire Shard, 6 Wind Shard and 3 Earth Shard.

The chain crosses two disciplines — Blacksmith to Lv 35 and Carpenter to Lv 25 — so no single class can finish it unaided.

3 of the 4 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
