Pick every unit in (Random 1 units from (Units within 350.00 of (position of LightningSwordThousandBlades) matching (((Picked unit) is in Heroes) Equal to False))) and do (Actions)
Loop - Actions
Unit - Kill (Picked unit)
Why does this have a chance to kill the Caster (LightningSwordThousandBlades) who is in the group Heroes?
