Mixing two medicines together to combine their effects is a risky step to
take, but trained alchemists and herbalists who know what they're doing can
make it work. This skill combines the effects of two salves, so they can both
be applied at the same time.
Syntax: use blend salves at <salve 1> and <salve 2>
Higher skill lets you mix stronger salves with more effects, however, the
second salve can only have ONE effect which is blended into the first. It
should be noted that mixing strong and weak salves always gives a weak result.
