Does Dispel Magic end the spell for everyone affected or just the target?


An opposing Cleric casts Bless on 3 of its allies who then immediately move around the battlefield to start attacking. Concerned that the buff will create an issue, I cast Dispel Magic on the nearest one.

As the target spell is 3rd level or lower, the dispel succeeds automatically.

My question is, does this end the spell for all 3 of the initial targets, or just the one that I targeted?
