Ancient Horadric texts record that Andariel and the other Lesser Evils once overthrew the three Prime Evils - Diablo, Mephisto
and Baal - banishing them from Hell to our world. With this betrayal weighing against her, Andariel's presence in Sanctuary can
only mean that the forces of Hell are once again aligned behind Diablo and his Brothers. While it is clear that the Maiden of
Anguish is acting on behalf of Diablo to prevent anyone from following him eastward, it is also clear that she must be destroyed
if the Lord of Terror is to be stopped.
Tips and Other Additional Information
Andariel has a deadly poison attack she will cast when you get up close. Whenever possible fight from a distance. Open up a Town Portal
before fighting Andariel so that you can easily get back to your body if you die. You can also use this Town Portal to escape if
the fight goes badly. You can lead Andariel in circles around
the little lake before the two doors into her lair if you need time to heal or for Healing Potions to take effect.
