Antimagic Pulse

You hurl a beam of light-blue light which bursts into a pulse of antimagic. Each creature and magical item in a 10-foot radius sphere centred on a point within range that you can see, suffers the effects of antimagic until the end of your next turn. 

Magic items lose their magical properties, and creatures inside the pulse’s blast radius cannot cast spells of 4th level or lower, until the end of your next turn. Creatures inside the blast radius concentrating on a spell of 4th level or lower dispels the magic. 

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the antimagic pulse dispels magic equal to or lower than the level of which this spell is cast, and creatures effected by the pulse cannot cast spells equal to or lower than the spell level this spell is cast at.
