High Steel Scutum

Taken all the way down to base materials, one High Steel Scutum is 3 crafting steps deep and needs 4 intermediates — High Steel Ingot ×2, Gagana Leather ×1, Koppranickel Nugget ×1 and 1 other — which resolve to 6 distinct raw materials totalling 32 units, plus 27 crystals.

That bill outweighs 10,750 of the 13,602 recipes tracked here and 1,133 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 15 Fire Crystal, 6 Earth Crystal, 3 Ice Crystal and 1 other kind.

The chain crosses four disciplines — Armorer to Lv 62, Blacksmith to Lv 62, Goldsmith to Lv 61 and Leatherworker to Lv 61 — so no single class can finish it unaided.

5 of the 6 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
