Steel Chainmail

Taken all the way down to base materials, one Steel Chainmail is 3 crafting steps deep and needs 5 intermediates — Steel Rings ×3, Undyed Velveteen ×1, Steel Ingot ×3 and 2 others — which resolve to 4 distinct raw materials totalling 13 units, plus 23 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 599 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 12 Ice Shard, 6 Fire Shard, 3 Lightning Shard and 1 other kind.

The chain crosses three disciplines — Armorer to Lv 28, Blacksmith to Lv 26 and Weaver to Lv 24 — so no single class can finish it unaided.

3 of the 4 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
