Growth Formula Epsilon

Taken all the way down to base materials, one Growth Formula Epsilon is 2 crafting steps deep and needs 1 intermediate — Quicksilver ×1 — which resolves to 3 distinct raw materials totalling 7 units, plus 4 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 980 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 1 are burned by the intermediates, so the real crystal cost is 3 Water Crystal and 1 Water Shard.

Every step is Alchemist work, from a Lv 1 intermediate up to the Lv 51 finish, so one class covers the whole chain.

2 of the 3 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Growth Formula Epsilon is itself consumed by 11 further recipes, spanning three of the eight crafting classes.
