A surprise in every bottle! When drunk, a potion of mutation first removes 2-3 mutations, then adds 1-3 random mutations (each with a 60% chance of being good), then has a 50% chance to add one good mutation. This potion is affected by mutation resistance. In addition, characters who are already mutated are less likely to gain further mutation.

Followers of Zin incur penance if they knowingly drink this potion at less than ****** (160) piety. Once that piety threshold has been reached, however, Zin suppresses the mutation-adding effects of the potion, so followers can drink it to only remove mutations.

Note that Ghouls cannot use this potion, but drinking an unidentified potion of mutation will cause them to suffer stat drain.

Strategy

Other than the god Jiyva, potions of mutation are your only way of removing any bad mutations you come across. Therefore, you should use them wisely. Generally, you shouldn't quaff them in the hopes of getting a good mutation.

History

• Prior to 0.27, potions of mutation removed 2-4 mutations and provided a guaranteed good mutation.
• Prior to 0.21, potions of mutation removed 2-6 random mutations instead of 2-4.
• 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.
