Riviera Lantern

Taken all the way down to base materials, one Riviera Lantern is 3 crafting steps deep and needs 4 intermediates — Bronze Plate ×1, Undyed Hempen Cloth ×1, Bronze Ingot ×2 and 1 other — which resolve to 4 distinct raw materials totalling 9 units, plus 7 crystals.

That bill outweighs 5,492 of the 13,602 recipes tracked here and 519 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 5 are burned by the intermediates, so the real crystal cost is 2 Fire Shard, 2 Ice Shard, 2 Lightning Shard and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 14, Weaver to Lv 2 and Blacksmith to Lv 1 — 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.

Riviera Lantern is itself consumed by 1 further recipe, all of them Alchemist recipes.
