Antimagic field

The caster created a 10 foot sphere radius around it that removed the magical forces of the univerce around it. The sphere made all magics withing non existent, as it followed the caster all spells would seize and magic weapons became mundane. The sphere could not be disspelled or cancelled by aother animagic field and if a magic item leaft the field it would regain its magical properties. Any summoned creatues would dissapear in the field but when the field left the space where the creature was it would reapear.
