I just spent... like 1 hour running around tarrant looking for a beggar so i can lose some good points.
Isn't this the other way around? Beggars are for boosting your PC's goodness; if you want to boost your evil, pick pocket some shopkeepers or other NPCs at random.
11 DERVISH ROAD.
Tarant Robed Figure
Outside the Taverns in both Stillwater and Durnhold. Durnhold has a halfing model for the beggar the other two are both robed figures.
Yeah, beggars loiter outside of taverns; if there's no one there, then that town doesn't have one. I think you found all of them; if you still need to boost your goodness (or vice versa) then accept some appropriate quests.
What's your goal here? Are you trying to qualify for a particular quest, or to add a specific follower? Or something else?
