Void Shield

You conjure a shield of void energy that surrounds you, absorbing incoming attacks with the chaotic power of the Eldrazi. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from magic missile.

Additionally, any creature that hits you with a melee attack while the shield is active takes 1d8 force damage as the void energy lashes out at it.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the force damage increases by 1d8 for each slot level above 1st.
