Dimensional Barrier

This spell releases a wave of arcane energy around the caster, hardening the barrier between dimensions in a small radius. This spell is cast as a reaction to a creature you can see beginning a movement via teleport. Until this spell ends no creature including the one that triggered this spell can begin or end a teleport move within the spell’s range.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the radius increases by 30 feet per spell level.
