Ruthenium Lorica of Maiming

Taken all the way down to base materials, one Ruthenium Lorica of Maiming is 3 crafting steps deep and needs 5 intermediates — Ruthenium Ingot ×3, Ihuykanite ×1, Mountain Chromite Ingot ×1 and 2 others — which resolve to 7 distinct raw materials totalling 36 units, plus 71 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,196 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 32 Fire Crystal, 16 Wind Crystal, 8 Ice Crystal and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 93, Blacksmith to Lv 92, Goldsmith to Lv 92 and Weaver to Lv 91 — so no single class can finish it unaided.

All 7 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
