Dragon Age: Origins Cheats, Codes, Hints, Tips
Cheat: Duplicate Items
You can duplicate gear, ingredients, potions, and other stuff as long as you already have two copies of the item you want to duplicate. It is best to only have the items you want to duplicate in both your Junk inventory and the merchant's. Put at least two of the item you want to copy in the "Junk" section of your bag. Go to any merchant and press sell all the junk in your bag. Then, select the item from the merchant's side, and buy back all but one of the item. Next, select it when it is in your inventory again. Press TRIANGLE followed by X very quickly. This requires precise timing and may require a few attempts, but it becomes easy to do after a few tries. You can keep repeating the process until you have 99 of the item. You can use this glitch with any of the Tomes as well to give your character all magic abilities max attributes by duplicating the Tomes.
Cheat: Unlimited Enhancement Crystals for Shale
In Redcliff, convince the innkeeper to join the fight. This will leave the barmaid in charge. Ask her for supplies and she will give you anything in the shop for free. Leave town and go to camp. Come back and get more supplies. Every time you return she will have a random assortment of the current and lower tier below crystals for Shale. They start to sell for 1 Gold Piece after you reach the "Cear" tier.
Note: Leaving the town before defending it will result in a lot of dead villagers, possibly the barmaid as well.
Hint: Easy Ceremonialist and Sacrilegious Trophies / Achievements
To collect both the the Sacred Ashes Trophies / Achievements (Ceremonialist and Sacrilegious) quickly without replaying the entire game, save your game before you ascend the stairs to the ashes. During the scene, collect a pinch of ashes and then put blood in the ashes. Allow yourself to be killed afterward and reload your save. This time, collect the ashes but don't put the blood in. Leave the temple and fight the disciples waiting for you to get the second Trophy / Achievement.
Cheat: Free Specialization Books
The Specialization Books that vendors sell can be attained without spending any gold. Save your game, then purchase the book. You will get a message on screen that says "Specialization Unlocked." Load the game that you saved before buying the book. You will have the Specialization unlocked and the gold.
Cheat: Level Up Glitch
During the Tainted Blood mission in Ostargar, collect the three Vials of Darkspawn Blood but avoid collecting the Grey Warden Treaties. After you have the vials, talk to Duncan and choose the conversation option "We have the blood, but not the scrolls." The conversation will end and you'll get experience! You can repeat the conversation and get the experience each time -- you can do this all the way up to the level cap at 25 (if you are patient)! You can click through the conversation fairly quickly once you've done it a few times.
