A 20-foot-radius immobile dome of nullifying magic forms around you and everything else within its area. The dome is completely spherical, passing harmlessly through physical obstructions. The dome lasts until the start of your next turn.

Up to 30 creatures of Medium size or smaller, 5 large creatures, or 1 huge creature can fit inside the dome with you. Spells and other magical effects can't extend through the dome or be cast through it, and any spell that comes into contact with it is dispelled. Breath weapons are also incapable of passing through the dome. Creatures and weapon attacks are able to pass through the dome. The only thing capable of rendering the dome useless is a wish spell specifically worded to ensure it does not function, the dome even dispelling antimagic field.
