If you are adjacent to more than one participant, you can power through the first to strike a second target. You make one System Check and compare the result of that Check to each individual target’s Defenses to determine if that target is hit.
Each Rank of Wide Swing allows you to attack one additional adjacent target. So, with Rank 4 Wide Swing, you could attack up to 5 different targets.
Damage is divided equally among all targets successfully hit.
