Action
At your behest, the shadows themselves grip at your foes, pulling and dragging like quicksand. Choose 4 squares within 20 feet of you that are in dim light or darkness . These squares become areas of magical darkness which are treated as difficult terrain and can’t be illuminated except by magic, such as the light spell. This effect lasts until the end of your next turn.
