Armorer's Stall

Taken all the way down to base materials, one Armorer's Stall is 3 crafting steps deep and needs 10 intermediates — Dwarven Mythril Ingot ×4, Titanbronze Ingot ×4, Dwarven Cotton ×3 and 7 others — which resolve to 12 distinct raw materials totalling 106 units, plus 173 crystals.

That bill outweighs 13,485 of the 13,602 recipes tracked here and 1,425 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 56 of those crystals go into the final step; the other 117 are burned by the intermediates, so the real crystal cost is 70 Fire Crystal, 28 Earth Crystal, 28 Ice Crystal and 4 other kinds.

The chain crosses four disciplines — Armorer to Lv 78, Blacksmith to Lv 78, Weaver to Lv 78 and Carpenter to Lv 26 — so no single class can finish it unaided.

11 of the 12 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, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
