You create a shimmering emerald barrier that completely blocks extradimensional travel.

Once dimensional lock is in place, extradimensional travel into or out of the area is not possible. Forms of movement barred within the radius of the emanation include Astral Projection, Blink, Dimension Door, Ethereal Jaunt, Gate, Maze, Plane Shift, Shadow Walk, Teleport, and similar spell-like or psionic abilities.

A dimensional lock 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 attack forms. Also, the spell does not prevent summoned creatures from disappearing at the end of a summoning spell.

Augment: You can augment this spell in one or both of the following ways:

1. For every additional spell point you spend, this spell’s radius increases by 5 feet.

2. If you spend an additional 4 spell points and 1000XP, the spell’s duration increases to permanent.
