Splash damage

Splash damage is a term used in StarCraft and StarCraft II 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 usually decreases the further the affected units are from that point. Splash damage is most effective versus large groups of weak units. Some attacks with splash damage may damage friendly units as well. Splash damage will also damage cloaked units even if they are not detected.
