An immobile, faintly shimmering barrier springs into existence in a 10-foot radius around you and remains for the Duration
Any spell of 5th Level
or lower cast from outside the barrier can't affect Creatures
within it, even if the spell is cast using a higher level spell slot. Such a spell can target Creatures
within the barrier, but the spell has no Effect
on them. Similarly, the area within the barrier is excluded from the areas affected by such Spells
At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, the barrier blocks Spells
of one level higher for each slot level above 6th.
