Places of Power are stone monuments marked with one of the Signs used by witchers to combat men and monsters. Drawing magic from these places grants a powerful boost to Geralt and enhances the Sign that is marked on the monument. The real boon to Places of Power is that they grant an additional Ability Point. It’s worth going out of your way to find all fifteen Places of Power in the game as early as you can, just to have an advantage in the earlier parts of the adventure.
The fifteen Places of Power in the game are spread evenly across three major locations: White Orchard, the combined regions of No Man’s Land and Novigrad, and the isles of Skellige.
