You create a protective barrier of ethereal energy, mimicking the otherworldly power of Xeno'jiiva. For the duration, you gain a +3 bonus to AC, and any hostile creature that makes a melee attack against you takes 3d6 force damage as the barrier retaliates.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the force damage increases by 1d6 for each slot level above 4th.
