When a creature of size Large or smaller hits you with a melee attack, you may use your reaction to cast this spell. As a consequence, you take no damage from the attack, and the attacker loses the rest of their turn and is left prone on the other side of you.

EDIT: Add this to the Wizard, Warlock, Sorcerer, and Bard lists.
