Mythrite Scutum

Taken all the way down to base materials, one Mythrite Scutum is 3 crafting steps deep and needs 3 intermediates — Mythrite Nugget ×4, Archaeornis Leather ×1 and Mythrite Rivets ×1 — which resolve to 4 distinct raw materials totalling 28 units, plus 23 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 988 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 15 Fire Crystal, 5 Earth Crystal and 3 Ice Crystal.

The chain crosses three disciplines — Armorer to Lv 51, Blacksmith to Lv 51 and Leatherworker to Lv 51 — so no single class can finish it unaided.

3 of the 4 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
