See Beyond Divinity HEX-code, Hint here!

Start game with stronger character
The first Act of Beyond Divinity, even on the easier settings, can be a
frustrating chore because your characters are so weak and the opposition is much
tougher. This cheat can help you start with stronger characters and avoid
prolonged and epic battles with lowly Level 2 skeletons.

To start a game with a stronger character open the "Beyond Divinity" folder on
your hard drive, open the "Common" folder, and double click on the
"CharSelStats.dat" file. You'll be promoted to select a program to use to open
the file; select NotePad. [Be sure to either back up this file, or write down
the default attributes, before changing any text !]

Using NotePad, change the attribute numerals for each character class (Warrior,
Wizard, or Survivor, whichever one applies to the character you intend to use)to
higher values. For example, if you intend to play as a wizard, starting with a
level 9 Intelligence is helpful; for a warrior, upping the Strength or Agility
attribute to 10 or greater will allow you to promptly use some of the early-game
armor and weapons, rather than selling them or lugging them in your inventory.

When you're finished, Save the changes and start a new game.

Duplicate Items rating
You can duplicate items and money the same way as you can in Divine Divinity.
Select the item from your inventory drag across to plane as you drop the item
you press Ctrl+L (Quick Load) the same time the item is falling. This may take
some practice to get use too!

Instant Battlefields
Once you have located one or more of the battlefield keys during the first act
you must add them to your inventory - to do this you will need to drag and drop
the key into your inventory. These keys will stay with your character throughout
each act. When entering a new act simply click on each key to activate it and
the battlefields will become available - there is no need to locate the keys
specific to each act.
