Infinite Armor Points GlitchAdded 15 Mar 2011, ID #3739
This glitch can be performed using Hawke and Aveline and can be done at any point in the game. To do it equip, then un-equip, and then re-equip a shield. When you do this your Armour Number/Percent will rise, this can be done as many times as you want until you've maxed out.
Infinite Ability Points GlitchAdded 15 Mar 2011, ID #3738
To be able to perform this glitch you must first obtain plenty of the Makers Sigh potion. When you have a large quantity begin by assigning your available abilities to your 'Tactics' menu using the Makers Sigh potion (the Makers Sigh postion will remove ALL your abilities). Save and reload that save and go into your 'Ability' menu and you will see that the abilities you assigned to your tactics are already unlocked and you will still have ALL your unassigned Ability points. You can either use the Makers Sigh potion again and save then reload or you can assign your points to other abilities and put them in your 'Tactics' menu and repeat the rest of the glitch for more Ability points. This glitch also allows you to unlock certain abilities in classes without having to go through the entire skill tree.
