Bismuth Shield

Taken all the way down to base materials, one Bismuth Shield is 2 crafting steps deep and needs 3 intermediates — Bismuth Ingot ×1, Red Pine Lumber ×1 and Saiga Leather ×1 — which resolve to 5 distinct raw materials totalling 16 units, plus 39 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 15 Earth Crystal, 8 Fire Crystal, 8 Ice Crystal and 1 other kind.

The chain crosses four disciplines — Armorer to Lv 85, Blacksmith to Lv 84, Carpenter to Lv 84 and Leatherworker to Lv 84 — so no single class can finish it unaided.

4 of the 5 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, Bismuth Ingot has the widest use: 104 recipes call for it, spanning six of the eight crafting classes.
