Don’t!

You entreat your attacker to reconsider their actions. The attacking creature must make a Charisma saving throw against your spell save DC. On a failure the attack automatically misses.

At higher levels: When you cast this spell using a spell slot of 4th level or higher, you can negate one other attack that is part of the same action for each slot level above 3rd. The creature must make separate Charisma saves per attack targeting you.
