A few rare magic items confer a magic save against the effect of a spell but do not dispel the spell itself. For example, the Black Armour of Nagash as worn by the special character Nagash saves against the effect of a spell on the D6 roll of a 4+. In these cases it is possible for an individual model to remain unaffected by a spell which affects the rest of his unit.

It is important to distinguish between a Natural Dispel (which dispels the spell being cast) and a magic save (which merely avoids the effect of a spell). Magic saves are much rarer, and usually apply only to individual models, giving them a certain amount of extra protection from spells.
