Book Bash

You imbue your spellbook with power and swing it with magical impetus. Make a melee spell attack against the target. You have advantage on the attack roll if the target is large or bigger. On a hit, the target takes 1d8 bludgeoning damage, and your movement doesn't provoke opportunity attacks until the end of your turn.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
