The text of Prismatic Wall states:
You create an opaque wall of shimmering, multicolored light. The wall is straight and vertical, stretching 60 feet long and 30 feet high. You must form the wall in an unbroken open space so its edges don't pass through any creatures or objects, or the spell is lost.
I had a question about this... isn't this kind of unusable? It requires a space that is 60 feet wide and 30 feet high, meaning it can't be used indoors in the vast majority of indoor spaces or the edges would brush up against some wall or ceiling or another, which I can't imagine is anything other than 'an object'. I'm really struggling to see how you could use this well given how enormous and unwieldy it is. I rarely see battles where there is that much open space with no objects whatsoever. Since you can't shrink the wall to fit, and can't reshape it (that would kind of step on the toes of the Prismatic Sphere spell one spell level up) it seems nearly unusable. It would either be impossible to place or fairly simple to go around/over/underneath. Similarly, Prismatic Sphere shares the same issue. If you're standing on the ground, the spell fails. Are the ground and walls and ceiling not considered objects? There's no definition that I am aware of for what exactly constitutes an 'object'. Am I missing something?
EDIT: It also seems strange considering a very similar spell, Chromatic Wall, does not break the wall on objects, only on creatures.
