Dimensional Lock

Once you cast this spell all teleportation is blocked in a 100ft radius sphere centered on a point you can see in range. Creatures can not enter or exit the area or move inside of it by means of teleporation. The caster and a number of creatures chosen by the caster equal to their spellcasting ability score modifier are able to ignore this spells effect.

This effect doesn't block teleportation from gods and other divine creatures similar to gods.

At higher levels : If cast at 8th-level or higher it becomes permanent until dispelled and the caster can choose which creatures are affected.
