Smartcasting is a micromanagement tool in StarCraft II. When multiple units are given the same spell order, only one of them will comply, preventing a serious waste of spellcaster energy.
List of Smartcast Abilities
Not all unit abilities are subject to smartcasting.
For instance, the stalker's Blink ability does not use smartcasting. When a group of stalkers are ordered to Blink to an area, all the stalkers will blink.
