Steadfast Ward

An immobile, faintly shimmering barrier springs into existence in a 10-foot radius around you and remains for the duration. You and up to nine creatues of medium or smaller size you choose that are within it have +5 bonus to AC. The bonus to AC ends for them is they leave the radius and the spell ends if you leave it.
Any spell of 3rd level or lower cast from outside the barrier can’t affect creatures or objects within it, even if the spell is cast using a higher level spell slot. Such a spell can target creatures and objects 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.
Additionally any ranged weapon attacks on a target within it the radius originating from outside the radius, roll with disadvantage on the attack roll. 
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the barrier blocks spells of one level higher for each slot level above 3rd.
