A Prismatic Wall/Sphere is destroyed by a Mage's Disjunction. However, is a person behind/within the Prismatic defence protected from the Disjunction?
Disjunction states that it has a chance to take down Anti-magic field, and if it doesn't then items within are not disjoined. Which implies that if does take it down, then items within are disjoined.
So does the same apply to a Prismatic Sphere? If a disjunction is targeted outside the sphere (I would say it can't be targeted inside the sphere, from the outside), then the sphere will go down. But what happens to things inside the sphere? The behaviour of Anti-magic field would suggest to me that things within/behind the Prismatic Sphere/Wall will not be protected.
At a lower level, what would a Wall of Force? Does that block the effects of a Disjunction, even though it itself is destroyed?
