@JeremyECrawford Dispel Magic says "Choose one creature, object, or magical effect within range." Is it possible to choose a magical effect on a creature (e.g. Bless) without targeting the creature? Or is the intent that you choose a tangible/perceptible effect like Web?

Dispel magic can target a discrete magical effect on a creature or an object, provided that effect is choosable. In other words, you have to be aware of it to be able to choose it as the target. #DnD https://t.co/WESHPeWoF4

So you could remove a spell like Slow without removing other spells on the creature if you’re aware they’re under the effects of the Slow spell? That's correct.

Last question: if you targeted the Slow spell directly (as opposed to the creature) in that situation, would it end for all other targets too or only that one creature? Just for the creature. The target in this case is the magical effect of slow on that creature, not the entire spell and all its targets.
