In Alan Wake 2, the writer can collect Words of Power, which allows him to strengthen his skills. Words of Power take the form of spiral graffiti sprayed in light-sensitive paint. When Wake shines his torch beam on the spiral, another skill point will be added to his collection.
To make sure that a Word of Power has been successfully collected look out for an old film-like filter. A notification will also pop up, encouraging the player to make their choice.
