  • Minthara will still appear at Moonrise Towers if she was knocked out in Act I.

As for how to recruit her;

  • Commit a crime in front of her when you're ready to annihilate the camp
  • Knock her out
  • Kill everyone else
  • And then just talk to Halsin, do the party and continue the story ^^
