There has been a lot of debate in my D&D group about the specific wording of Dispel Magic which were not answered by the D&D Sage Advice Compendium:
Choose one creature, object, or magical effect within range. Any spell of 3rd level or lower on the target ends. For each spell of 4th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. On a successful check, the spell ends.
What happens if one chooses a "magical effect"?
In a similar question I asked whether or not Dispel Magic could target multiple effects on a single creature or object: How exactly does the Dispel Magic spell work with multiple effects?
The answer there was that Dispel Magic does have a plural effect (it can remove more than one effect with a single casting). If this is the case, then I'm left to question what exactly is meant by targeting a "magical effect".
Targeting a creature is obvious. Remove all spells on that creature.
Targeting an object is similarly obvious. Remove all spells on that object.
However could I, for instance, target the magical effect of "Invisibility" and remove all instances of Invisibility within a 60-foot radius of the caster? Could I target "Glyph of Warding" and remove all glyphs in the area?
