I gave up at frolle's wife, she seems to have more hp than you, and bandages don't heal enough, so it's all just damage luck
Bandages heal 5, she deals random form 5 to 10. Therefore it’s never a good idea to heal. So your only choice is to fight. As far as I can tell, you deal as much damage as her, and she has more health, so it’s entirely random if you win or not. Combine that with a long sequence to get back to the fight, and you have a recipe for a frustrating encounter.
