Astral Oil ★

Nothing in this list is craftable in turn, so a batch of 4 Astral Oil is a single step: 5 units of material drawn from 3 base items, plus 3 crystals.

That bill outweighs 4,201 of the 13,602 recipes tracked here and 826 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

2 of the 3 raw materials come out of the ground, and 2 of them are time-gated: Astral Moraine (0:00, 12:00) and Seventh Heaven (4:00, 16:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Astral Oil is itself consumed by 12 further recipes, spanning four of the eight crafting classes.
