Eulmoran Inner Wall

Taken all the way down to base materials, one Eulmoran Inner Wall is 3 crafting steps deep and needs 7 intermediates — Dwarven Cotton ×4, Mortar ×4, Pixie Cotton ×4 and 4 others — which resolve to 6 distinct raw materials totalling 60 units, plus 92 crystals.

That bill outweighs 13,112 of the 13,602 recipes tracked here and 1,931 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 78 are burned by the intermediates, so the real crystal cost is 69 Lightning Crystal, 11 Wind Crystal, 8 Water Shard and 1 other kind.

The chain crosses three disciplines — Weaver to Lv 78, Carpenter to Lv 30 and Alchemist to Lv 20 — so no single class can finish it unaided.

All 6 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, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
