Barrier

A shimmering antimagic barrier appears around a creature you can see within 30ft. The next spell that targets that creature is nullified by the barrier and the barrier is consumed.

Targeted Effects. Spells and other magical effects, such as magic missile and charm person, that target the creature or an object held or worn by that creature have no effect on that target.

Areas of Magic. The area of another spell or magical effect, such as fireball, can't extend past the barrier and consume the barrier. If the creature walks into a area affected by a magic spell the spell has no effect for one round and the barrier is consumed. For example, if the creature walks into a wall of fire they are not effected and the barrier is consumed.

Spells. Any active spell or other magical effect already on a creature or an object worn or held by the creature at the time the barrier is cast, do not consume the barrier and continue as normal.

Any spells cast by the creature or active effects from magical objects or items worn or held by the creature covered by the barrier, after the barrier comes into affect, consume the barrier.
