I'm trying to understand the limits of this spell, so far the only example in my mind that's unaffected are transmutation spells that are instantaneous? Such as "Erupting Earth?"

I might be wrong though, but I'm eager to make a list of unaffected spells that can't be disrupted with "Dispel Magic."

Thanks in advance to anyone who answers this!

Anything with a duration of Instantaneous is immune to dispel magic as the magic doesn’t last long enough to be dispelled, not just transmutation spells

Thank you so much, I really appreciate it!

Eventually, based on the replies here, I'll make a separate post on a full list of spells unaffected by dispel magic for players and dungeon masters alike, but thanks again for the reply!

I think prismatic wall is also unaffected by dispel magic.
