Re: oakvale pirate tresure
Right, I'll help you out. Once you have spoken to the ghost, make your way down to the pier/walkway/wooden thing on the beach. As you look at the pier and out to sea, go the the left of the pier, go right up to the side of it and your shovel should flash up to use (360) DIG and you should recieve 500 gold coins! You think, wow what a random thing thats not treasure I'll keep it, It's the treasure! Take your 500 gold coins to the wife who is standing farther down the beach, hand over the 500 coins and she talks, blah blah.
Head back to the ghost and he will thank you by telling you the location of a secret treasure that he buried. Go to the Oakvale graveyard to the north of Oakvale, (you know that) In the graveyard is a statue with a big axe, and dig on the side that the axe is being held, (left as you look at it)
And surprise! there's your treasure, quest completed, I'm not telling you what the treasure is.
I hope this helps you and is easy to follow. Happy playing
