Magical box

The Magical box, or magic box, is a micromanagement technique in StarCraft. It enables multiple spellcasters to unleash their spells at the same time, but in slightly different areas of the screen.

If spellcasting units of the same type are put into a small "box", the units will move in formation and cast spells in formation. The spells must be targeted "outside" second box, otherwise they will clump together.

Magic boxes work best with small numbers of casters, such as four vultures or high templar.
