Bladed Lantern Shield

Taken all the way down to base materials, one Bladed Lantern Shield is 3 crafting steps deep and needs 4 intermediates — Iron Ingot ×2, Steel Plate ×1, Steel Rivets ×1 and 1 other — which resolve to 3 distinct raw materials totalling 16 units, plus 22 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 14 are burned by the intermediates, so the real crystal cost is 11 Fire Shard, 7 Ice Shard and 4 Earth Shard.

The chain crosses two disciplines — Armorer to Lv 37 and Blacksmith to Lv 29 — so no single class can finish it unaided.

2 of the 3 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
