How does the Retcon system work?
To retcon a power, you go to the Powerhouse (a building available after the tutorial) and speak with a trainer. You will be able to completely undo your purchases (Powers, Talents, Superstats, Travel Powers & Advantages), for a cost. This cost to retcon powers increase as your base level increases. Changes made in the Powerhouse are not permanent until you leave so you can retcon multiple times to try stuff out.
