Jack-o'-lantern

Taken all the way down to base materials, a batch of 3 Jack-o'-lantern is 2 crafting steps deep and needs 2 intermediates — Beeswax ×1 and Maple Syrup ×1 — which resolve to 4 distinct raw materials totalling 6 units, plus 4 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 531 of the 1,058 Culinarian ones, and 4,464 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 2 Fire Shard and 2 Water Shard.

The chain crosses two disciplines — Culinarian to Lv 10 and Alchemist to Lv 10 — 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, Beeswax has the widest use: 26 recipes call for it, spanning six of the eight crafting classes.
