As an action you create a shimmering emerald sphere of 120 feet radius centered on you. This sphere completely blocks extradimensional travel.

Forms of movement barred by a dimensional anchor include blink, dimension door, etherealness, gate, maze,misty step, plane shift, teleport and similar teportation abilities. This ability also prevents the use of a gate or teleportation circle for the duration of the spell.

A creature can break through the Dimensional Anchor if it succeeds an Intelligence saving throw against your Spell DC.
