The noise of battle grows faint, and the flash of blade and spell fades away, as you focus all your senses on your target.

Minor Action      Ranged 10

Target: One creature

Effect: When you attack the target, you take no penalties to attack rolls because of cover, superior cover, concealment, or total concealment. This benefit lasts until the end of your next turn.
