Here are a few quest tips for those of you who may not know:
As mentioned in other topics, on the Robbed Woodpile quest - take back at least 15 pieces, not the requested 5. Extra reward is noble upper armor.
On the Obtaining Grapes quest when he gives you 60 minutes to kill the antelopes, make sure you report back with EXACTLY 57 minutes on the clock. Numbers don't matter here, just the clock. Kill the bare minumum (which I think may be as low as 3), and report back at 57 minutes. Extra reward is a Shrewd Amulet lvl 1.
When you are given a quest to collect something, always take back more than you need.
When you are given a quest to kill something but they don't specify how many to kill, always kill extra. The more the better.
I remember once when Scandal and I were doing a quest (I can't remember which one), and had to collect something. Scandal took back the required number and got some mage gloves. I took back one extra and got heroic figther gloves. Scandal, maybe you remember which one?
