Subtopic: how to break a quest.
Walk away in the middle of the conversation, say things just to try to confuse the NPC, try a lot of RP words in conversation with a NPC (EX: How farest thee, my good man, I come to you looking for a quest worthy of a future hero, do you have any such tasks I could do to further prove myself?" vs "Give me a quest" or "can I help you"
If you get stuck, I do not recommend exiting PS anymore than I would recommend turning off your computer by pulling the plug out of the wall. You might be ok, but try to read what was said and try to finish it. I can not think of a single instance in PS anymore where logging off and then on solves any quest or completes any tasks.
I hesitate to recommend guides through tutorial, only there for last resort. IF it is so hard no one can finish it without guide, it should be made more clear. I found that if you read and think about what you are saying, it is not that hard, and is a good tutorial for life in Yliakum.
of course if you just want to kill stuff and not read or think, there are rats there :-P
Happy hunting.
