Can prismatic wall be dispelled?
A prismatic wall can’t be dispelled, and is unaffected by an antimagic field (and, implicitly, other forms of antimagic, like a beholder’s central eye beam). Instead, each layer of the wall must be destroyed individually, and only through very specific means.
What happens if you destroy the Prismatic Wall?
(Typically, a creature that is on a plane that isn’t its home plane is banished home, while other creatures are usually cast into the Astral or Ethereal planes.) This layer is destroyed by a dispel magic spell or a similar spell of equal or higher level that can end spells and magical effects.
How does a creature pass through the Prismatic Wall?
When a creature attempts to reach into or pass through the wall, it does so one layer at a time through all the wall’s layers. As it passes or reaches through each layer, the creature must make a Dexterity saving throw or be affected by that layer’s properties as described below.
How long can you stay near the Prismatic Wall?
You and creatures you designate at the time you cast the spell can pass through and remain near the wall without harm.
