Not all alchemists leap straight into the delicate and sometimes unpredictable
art of potion mixing. Some take the time to work with a slightly simpler
system and make salves instead. Salves are various balms, ointments, and
creams applied to a person or object to give it some special power. Making a
salve requires only a bit of some material and a plant, plus a mortar and
pestle (an alchemist's hammer can act as a pestle) to grind the ingredients.
Syntax: use mix salve at <material> and <plant>
