Anti-Magic Wall

A glowing wall shimmers into existence at a point you choose within range. You can make the wall up to 60 feet long and 20 feet high, or a hemispherical dome or sphere with a radius of up to 10 feet. The wall lightly obscures vision. 

When a spell is cast on a target or point that can only be seen through the wall by the spell’s caster,  you can force that creature to make a check using their spellcasting ability against your spell save DC. If they fail the check, the spell fails and has no effect. If they succeed on the check, the spell is not affected by the wall. 

When a spell is cast on a point on one side of the wall and its area of effect crosses the barrier, you can choose to block the spell’s effects from crossing the threshold of the wall. 

When fiends, celestials, and fey attempt to cross the wall, you become aware of the attempt no matter where you are and can force them to make a constitution saving throw. On a failure, they cannot cross the wall's threshold for one minute.
