Easy gold
Put your most expensive item in the junk section in your inventory. Find a merchant, enter the "Junk" section in your inventory, highlight the expensive item, then press Y followed by A very quickly. If done correctly, your item will be sold at twice its value. It may require a few attempts. Buy it back, and repeat the process as many times as desired. It is best if you use two fingers, with one on Y and another on A so you can press them almost simultaneously. It is recommended you either do this with a merchant that you have not sold any junk to before, or buy back all the junk you previously sold. This speeds up the process enough so that you can double the gold as fast as possible. Additionally, if the merchant has an item more expensive than the one you are selling, buy it, and use that instead to increase the amount of gold you get. If you have the Blood Dragon Plate, this can be easily done with the first merchant.

Easy experience
You can use the "Easy gold" glitch to basically get unlimited experience. Once you save the life of the Arl of Redcliffe, a soldier of his will appear in your party's camp. There will be a box for donating to the army. Enter the screen, and select the first option to donate 30 gold. You can do this as many times as desired to get a good amount of experience from each donation. If you just keep pressing A then X repeatedly, you will keep quickly donating large sums of gold, skipping through the dialog screens, and getting a lot of experience quickly. If you start getting low on gold, perform the "Easy gold" glitch again with the merchant in your camp. Note: Be careful, as enemies will also level as you do. If you get too high of a level and do not have the correct equipment, you can be quickly defeated.

In Ostargar, do the "Tainted Blood" mission that is unlocked immediately before you become a Grey Warden. Collect the three Vials of Darkspawn Blood, but not the Grey Warden Treaties. Return to camp, talk to Duncan, and report "We have the blood, but not the scrolls." You will exit out of the conversation, but still get the experience for the mission. You can repeat this as many times as desired. It does not take long to reach the level 25 cap if you skip the conversations to speed up the process.

Note: This trick requires you have the Trap Making ability. In Lothering, go to the right after exiting Dane's Refuge (near the center of Lothering). There will be a quest giver by the name of Allison. She will ask you to make traps, and requires three traps to complete the quest. Once you complete the quest, you will get a moderate amount of experience and 50 silver. You can repeat this quest as many times as desired; however, the quest will become unavailable as you progress through the game. To keep repeating the quest, go back to Dane's Refuge, and buy Trap Triggers. He has an unlimited supply of them. As long as you have Trap Making, create Spring Traps. Spring Traps only cost approximately 3 silver to create, and she requires three traps each time. Thus, it only costs you roughly 9 silver for the quest.

To get extra experience points early in the game, go to the city of Denerim as soon as you leave Lothering. Then, enter the "Wonders of Thedas" building, and purchase the Archivist's Belt. While it is equipped, you will get an experience point boost for everything in your Codex. Books will increase from 50 to 75 experience points.

Duplicate items
This glitch allows you to duplicate gear, ingredients, potions, and other stuff. First, you need at least two of the item you want to duplicate. The glitch is basically the same as the "Easy gold" glitch. Thus, it is best to only have the items you want to duplicate in both your and the merchant's "Junk" inventory. This help speeds up and organize things. Put at least two of the item you want to copy in the "Junk" section of your bag. Go to any merchant, and press Y to 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 Y followed by A very quickly. This requires precise timing like the "Easy gold" glitch 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. Some items will show in the merchant's inventory as being one row of 99, and another row of a different number (for example, 33). Sometimes the extra items can be taken and kept; however, other times they will vanish from your inventory. Be careful about taking the correct row. If you have the "Warden's Keep" downloadable content, you can store unlimited items in the bottomless chest so you will always have more if you ever run out and do not want to keep using this glitch. This glitch should also work with books that add Skill or Talent points. When you get any of those books, wait until you have two of them so you can make unlimited copies and max out your characters.

Free Specialization books
Save the game, then buy a Specialization book from a vendor. The message "Specialization Unlocked" will appear. Then, load your saved game, and you will have the gold back that you spent for the book, but the specialization will still be unlocked.

When you first arrive at your party camp, you will see Bodahn Fennick, the Dwarf trader. Speak to him, and view his wares. You will find two Specialization books, Ranger and Templar. Save the game, then buy one to unlock that Specialization. Reload your game, and buy the other one. You will now have both specialties unlocked and still retain your gold after reloading your game again. This works with all Specialization books.

Extra storage
In Lothering, go towards a bridge on the edge of town. There will be a bridge where a Dwarven father and son are getting attacked. If you save and are nice to them, they will be in your party's camp when you arrive shortly afterwards. They are merchants, and the son is an enchanting savant. The father has good items to start. Buy the items, using the "Easy gold" glitch if needed. He never seems to lose what you sell him. You can basically use him as free storage. This works well for players without the "Warden's Keep" downloadable content's bottomless chest, or if you do not want to keep traveling to Soldier's Peak to retrieve your excess inventory.

Extra backpack in Ostagar
When you arrive in Ostagar, buy the Backpack from the Quartermaster. Note: You should have enough money all long as you collected sell-able items and gear during the beginning storyline. Successfully complete the quest where you and the other recruits enter the Wilds; make sure you explore the entire map. Successfully complete the "Joining" ritual, and become a Grey Warden. Before attending the meeting with Duncan and the King, go back to the Quartermaster, and there should be another Backpack available to purchase at the same price as before.

Mass Effect reference
There is a book titled "Load Limit Reached" that you can find in the Orzammar underground section "The Dead Trenches", near the "Legionnaire Shrine" at the end of a broken bridge. The first line in the book is "Mass will have an effect". It mentions a Dwarf named Shepard, which is the same name as the main character of Mass Effect.

Portal reference
Note: You must have Sten in your party for this trick to work. At the end of the game, if you choose to perform the ritual with Morrigan, you will go to the crowning of the new king or queen. After the dialogue with Alistair, you can walk around and talk to your companions. Find Sten, and he will say "Where is the cake? They promised there would be cake. The cake is a lie..."

Superman reference
The following event is random and occurs while traveling on the world map. You will encounter a farmer and his wife who find a baby in a meteor crash, right after it happens. They decide to take the baby and raise it as their own. You get the Meteor Ore the baby came in. It can be made into armor by Wade in Denerim. A good way to get this event to occur is from one of the Chantry Board missions in Redcliffe. Travel straight from Redcliffe to Refugees.
