Mythrite Earblades of Slaying

Taken all the way down to base materials, one Mythrite Earblades of Slaying is 3 crafting steps deep and needs 3 intermediates — Mythrite Ingot ×1, Silver Ingot ×1 and Mythrite Nugget ×1 — which resolve to 5 distinct raw materials totalling 15 units, plus 14 crystals.

That bill outweighs 6,735 of the 13,602 recipes tracked here and 948 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 8 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 3 Wind Crystal and 2 Wind Shard.

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

All 5 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, Silver Ingot has the widest use: 157 recipes call for it, spanning eight of the eight crafting classes.
