You create a shield made of Wild Magic around yourself and one other friendly creature in range. The shield takes the form of a visible blueish purple aura.
Shielded creatures gain a +2 to their AC and an extra 1d4 to their saving throws against spells. Any creature that targets a shielded creature with a harmful spell must roll on the Wild Magic Surge table for every shielded creature they target.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can target one additional creature for each level above 2nd.
