Bismuth Goggles of Fending

Taken all the way down to base materials, one Bismuth Goggles of Fending is 2 crafting steps deep and needs 4 intermediates — Bismuth Ingot ×2, Grade 5 Vitality Alkahest ×1, High Durium Ingot ×1 and 1 other — which resolve to 9 distinct raw materials totalling 29 units, plus 55 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,028 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 8 Ice Crystal, 8 Water Crystal and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 85, Blacksmith to Lv 84, Goldsmith to Lv 84 and Alchemist to Lv 83 — so no single class can finish it unaided.

8 of the 9 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.
