Splash damage

Splash damage is a term used in StarCraft to refer to damage taken by units in the area surrounding a point of weapon impact. This damage is highest at the point of impact, and decreases the further the effected units are from that point. Splash damage is most effective versus large groups of weak units. However, some splash damage can also be carried over to units controlled by allies or oneself (depending on the type of splash damage).
