Essence Booster (Su): The alchemist applies this golden liniment to a weapon or suit of armor that has a tiered special ability (a special ability available in varying degrees of potency, such as light fortification or shadow). The affected special ability increases by one step (to moderate fortification or greater shadow, for example). If the item has multiple tiered special abilities, the alchemist chooses one to affect. The item’s enhancement bonus increases by 1 if it has no tiered magical qualities. The alchemist must be at least 8th level to choose this anointing.
