How do you get out of a quest on adventure quest?

Answer 1

Just die.

Update: You can die, however, if you feel like keeping that little bit of health you have; (though if you do die you usually get full health and reappear at battleon or places like the inn if that's where you started the quest at) you can just press flee which costs some sp. This way all you do is find twilly and click on him once, backout of the dialogue menu, and you will have full health again, you don't even have to ask him to heal you. Unfortunately, they do not have a button to quit mission, I believe that's what flee is for primarily.
