A non-mountable mount and ever popular NPC escort quest… :P Nice Choices 'n Consequences, though.
It would be funny if you use magic in the village and people start attack you for just healing someone.
In Shadow of Amn, the party would be attacked if they used magic-even harmless ones-in the city. I was tired of being warned and finally decided to fight them off. At that stage, my party was relatively strong and beat every law enforcement squad till they finally gave up, which was oddly satisfying.
