Silver Magnifiers

Taken all the way down to base materials, one Silver Magnifiers is 4 crafting steps deep and needs 4 intermediates — Silver Spectacles ×1, Clear Glass Lens ×2, Silver Ingot ×2 and 1 other — which resolve to 4 distinct raw materials totalling 12 units, plus 22 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 862 of the 2,216 Goldsmith ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 10 Water Shard, 8 Wind Shard and 4 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 25 and Alchemist to Lv 28 — so no single class can finish it unaided.

One intermediate outranks the result: Clear Glass Lens is a Lv 28 Alchemist recipe feeding a Lv 25 craft, so that step, not the last one, is the real gate.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.
