Embossed Book of Electrum

Taken all the way down to base materials, one Embossed Book of Electrum is 3 crafting steps deep and needs 5 intermediates — Book of Electrum ×1, Electrum Ingot ×4, Cobalt Ingot ×2 and 2 others — which resolve to 7 distinct raw materials totalling 28 units, plus 60 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,345 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 48 are burned by the intermediates, so the real crystal cost is 20 Wind Shard, 17 Water Shard, 13 Lightning Shard and 1 other kind.

The chain crosses four disciplines — Alchemist to Lv 49, Blacksmith to Lv 42, Goldsmith to Lv 42 and Weaver to Lv 38 — so no single class can finish it unaided.

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