Enchanted Aurum Regis Ink

Nothing in this list is craftable in turn, so one Enchanted Aurum Regis Ink is a single step: 7 units of material drawn from 3 base items, plus 5 crystals.

That bill outweighs 4,963 of the 13,602 recipes tracked here and 980 of the 1,591 Alchemist ones, and 9,374 recipes nest deeper.

2 of the 3 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Enchanted Aurum Regis Ink is itself consumed by 37 further recipes, spanning two of the eight crafting classes.
