Ivy Pillar ★

Taken all the way down to base materials, one Ivy Pillar is 3 crafting steps deep and needs 5 intermediates — Cut Stone ×6, Mortar ×4, Growth Formula Delta ×3 and 2 others — which resolve to 8 distinct raw materials totalling 50 units, plus 43 crystals.

That bill outweighs 12,777 of the 13,602 recipes tracked here and 2,069 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 18 Wind Shard, 11 Water Shard, 9 Water Crystal and 2 other kinds.

The chain crosses two disciplines — Goldsmith to Lv 50 and Alchemist to Lv 50 — so no single class can finish it unaided.

All 8 raw materials are gathered, and one of them is time-gated: Trillium Bulb (21:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
