Potion of beneficial mutation
|A potion which gives you a supposedly good mutation.|
Quaffing a potion of beneficial mutation immediately gives you a single mutation from the list of good mutations. This can include a boost to one of your stats, free resistances, and many more things that are (usually) helpful. Beware that some good mutations come with negative aspects, that piles of good mutations may make curing bad mutations much more difficult, and that each mutation you add on renders you slightly more vulnerable to silver damage.
This potion's effect may fail due to sources of mutation resistance that are not from equipment (such as being a halfling) or physiological conflicts (attempting to give nagas talons or tengu fangs, for example). Followers of Zin lose 10 piety if they knowingly drink this potion, even if Zin (or another source) blocks the mutation.
