Centred on the magician creates a fixed shimmering emerald barrier that completely blocks extradimensional travel centred. Forms of movement barred include: astral projection, dimension door, etherealness, gate, maze, plane shift, teleport, and similar spells or spell-like abilities. Once Null Teleport Zone is in place, extradimensional travel to or from the area is not possible.
This spell does not interfere with the movement of creatures already in ethereal or astral form when the spell is cast, nor does it block extradimensional perception or attacks. This spell also does not prevent summoned creatures from disappearing at the end of a summoning spell's duration.
At higher levels: For each spell slot above 7th used to cast Null Teleport Zone, the duration increases by half the magician's proficiency bonus in hours, and the length, breadth and width each increase by 50".
