Replica Sky Rat Ironclad Boots of Casting

Taken all the way down to base materials, one Replica Sky Rat Ironclad Boots of Casting is 2 crafting steps deep and needs 2 intermediates — Gagana Leather ×1 and High Steel Nugget ×1 — which resolve to 6 distinct raw materials totalling 11 units, plus 11 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 555 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 5 Earth Crystal, 3 Fire Crystal and 3 Ice Crystal.

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

3 of the 6 raw materials match a gathering node, none of them timed; the other 3 come 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.
