Infinite Gold:
In Mas Ora's district of The Munari City, go into the first building on your Left. Give the man there a loan of 1000 gold and he will give you a Bodril. Return here later in the game and he will offer to pay you back. Decline and tell him that you want to buy the Bodril for 5000 gold. Keep replying "no" to all of his other questions and you'll get more gold every time. Leave the area and he'll disappear.
Extra Experience:
Enter Miridian's Pass after beating Sepulchre and follow the wall on the Right. You will find a trail that leads Up into the mountains to a statue called "The White Lady". Equip Sangaril with a crossbow and enter first person view. Aim at the colored gongs in a specific order to raise the bridge Up to the statue. Once there, you will get 15000 experience points.
Shoot the gongs in this order:
First bridge - red, yellow, blue
Second bridge - orange, green, yellow, red
Third bridge - blue, orange, red, yellow, green.
