Is there an infinite health code for dragon age origins for Xbox 360?

I'm trying to kill the archdemon but I keep dying. Is there an infinite health code? If not, any suggestions on how to beat the archdemon?Is there an infinite health code for dragon age origins for Xbox 360?
No, Bioware doesn't seem to be known for actually putting codes into their games. If you haven't used them yet, you can use two Tomes of the Mortal Vessel to boast your attributes as far as you want without maxing out your skills preventing you from leveling up, by duplicating them. Unfortunately, that's only really an option before you set out to kill the Archdemon. In your case, you could set the difficulty down if you already haven't. There's no achievements based off the difficulty level so it won't affect anything in that way.Is there an infinite health code for dragon age origins for Xbox 360?
Play it is casual the first time.

I think it is tough the first time because when you play through the first time you don't always know what the best talents are or how to attribute points to magic, etc. Or.. even.. the best players to have on your team.
