Deeper Darkvision

You gain darkvision out to 60 ft. If you already have darkvision, its range increases by 30 ft. While in dim light or darkness, you have advantage on Perception checks to notice movement, silhouettes, and hidden creatures not behind total cover.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
