Excavator's Barrow

Taken all the way down to base materials, one Excavator's Barrow is 2 crafting steps deep and needs 1 intermediate — Excavator's Multi-purpose Plating ×2 — which resolves to 1 distinct raw material totalling 2 units.

That bill outweighs 3,130 of the 13,602 recipes tracked here and 386 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

The chain crosses two disciplines — Armorer to Lv 100 and Blacksmith to Lv 100 — so no single class can finish it unaided.

The single raw material does not appear in the gathering data, so the whole bill comes from vendors, drops or content this site does not track.

Of the intermediates, Excavator's Multi-purpose Plating has the widest use: 3 recipes call for it, spanning three of the eight crafting classes.

Nothing in the data consumes Excavator's Barrow: it is one of 181 end products among the 215 Armorer recipes at Lv 100.
