Rarefied Mythrite Bladed Lantern Shield

Taken all the way down to base materials, one Rarefied Mythrite Bladed Lantern Shield is 3 crafting steps deep and needs 3 intermediates — Mythrite Ingot ×3, Mythrite Rivets ×1 and Mythrite Nugget ×4 — which resolve to 3 distinct raw materials totalling 36 units, plus 31 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 7 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 4 Ice Crystal and 3 Earth Crystal.

The chain crosses two disciplines — Armorer to Lv 54 and Blacksmith to Lv 52 — so no single class can finish it unaided.

All 3 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, Mythrite Nugget has the widest use: 102 recipes call for it, spanning seven of the eight crafting classes.
