Counterstrike

You attempt to interrupt a creature in the process striking you. The creature needs to make a charisma saving-throw, and on a failed save be pushed back 15 ft, and they are unable to attack you until the start of your next turn. On a success, they're still pushed back but are still able to attempt the attack again.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you increase the distance they are pushed by 5 ft per additional spell level.
