|| A potion which mutates the drinker, removing several mutations then granting a few mutations, at least one beneficial.
|| Potion of Mutation
A surprise in every bottle! Potions of mutation first remove 2-6 mutations, then attempt to inflict 1-3 random mutations on you with each of those mutations having a 60% chance of being good, then give you one good mutation. Heavily mutated characters or those with any form of mutation resistance will often receive fewer mutations, potentially receiving zero. Followers of Zin incur a piety loss and a penance if they knowingly drink this potion.
Note that Ghouls cannot use this potion, but drinking an unidentified potion of mutation will cause them to suffer stat drain.
Prior to 0.20, potions of mutation just attempted to give 1-3 random mutations, with separate potions of beneficial mutation and potions of cure mutation.
