Rubedo

== ==
Rubedo is an additional, or secondary substance which is present in some alchemical ingredients in addition to the primary substance. All alchemical ingredients contain one of six basic substances: aether, hydragenum, quebrith, rebis, vermilion, and vitriol. There are also three additional substances: albedo, nigredo, and rubedo. Any given ingredient may contain only a single basic substance and potentially one additional, or secondary substance.
Rubedo potions: If all ingredients used to create a given potion contain rubedo as an additional substance, the resulting potion will increase the regeneration rate of vitality for 4 hours in addition to the potion's original effect.
