To activate this glitch it will require that you have access to the black emporium and have money available to purchase the potion "Makers Sigh" that resets all ability points, and attributes. Hawke comes preloaded with preset skills he is "supposed" to have. Meaning when you use a makers sigh and save, when you reload the game file these ability's will be filled. To take advantage of this follow these following steps. 1. Use makers sigh 2. Save your game. 3. Load your game 4. Check your ability points. You should have the amount that were taken away, plus the ability's that Hawke is "supposed" to have. For a rogue it will be around four - five points in the dual wield tree. 5. If you use another makers sigh, it will now add those ability's to the ability points available. I was effectively able to go from 20, to 45 within 5 minutes. You must save and reload each time you wish to do this again.
