Belah'dian Crystal Lantern

Taken all the way down to base materials, one Belah'dian Crystal Lantern is 3 crafting steps deep and needs 3 intermediates — Mythril Rings ×2, Mythril Plate ×1 and Mythril Ingot ×4 — which resolve to 3 distinct raw materials totalling 17 units, plus 36 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 660 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 16 Fire Shard, 16 Ice Shard and 4 Earth Shard.

The chain crosses two disciplines — Armorer to Lv 38 and Blacksmith to Lv 38 — so no single class can finish it unaided.

1 of the 3 raw materials matches a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
