Reinforced Mythril Elmo

Taken all the way down to base materials, one Reinforced Mythril Elmo is 4 crafting steps deep and needs 6 intermediates — Mythril Elmo ×1, Peiste Leather ×1, Mythril Plate ×2 and 3 others — which resolve to 5 distinct raw materials totalling 22 units, plus 69 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 808 of the 1,441 Armorer ones, and 1 recipe nests deeper.

Only 10 of those crystals go into the final step; the other 59 are burned by the intermediates, so the real crystal cost is 34 Fire Shard, 18 Ice Shard and 17 Earth Shard.

The chain crosses three disciplines — Armorer to Lv 44, Blacksmith to Lv 39 and Leatherworker to Lv 38 — so no single class can finish it unaided.

3 of the 5 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Mythril Ingot has the widest use: 135 recipes call for it, spanning seven of the eight crafting classes.
