Antimagic Circle

An aura of antimagic surrounds one creature of your choice within range. It can not  cast spells, take Magic actions, or create other magical effects, and those things can’t target or otherwise affect anything inside it. Magical properties of magic items for them or on anything they carry. 

They can not be affected by magic that gives positive effects, and they can not teleport into or out of it or use planar travel. Portals do not function for them.

Ongoing spells, except those cast by an Artifact or a deity, are suppressed for them if the effect is positive. While an effect is suppressed, it doesn’t function, but the time it spends suppressed counts against its duration.

Dispel Magic has no effect on them.

You have disadvantage on any checks you make to maintain concentration on this spell.
