<php>echo “<b>Benefit:</b>”;</php> As a standard action, you can make a single ranged attack with a bow that targets all creatures in a 60 ft. line.

If struck, creatures along this line take damage from your shot, though any precision-based damage is applied only against the first creature struck.
