An immobile, glimmering sphere forms around you. Any spell of 5th-level or lower cast from outside the sphere can't affect anything inside the sphere, even if it's cast with a higher level spell slot. Targeting something inside the sphere or including the globe's space in an area has no effect on anything inside.
The barrier blocks spells of one spell slot level higher for each slot level above 6th.
