Temporal Smite

The next time you hit a creature with a melee weapon attack during this spell’s duration, you weapon glows a deep purple and pulls a part of the time stream through the target, and the attack deals an extra 3d8 Psychic damage to the target. Additionally, the target must succeed on a Constitution saving throw or be stunned until the spell ends.

A creature stunned by this spell makes another Constitution saving throw at the end of each of its turns. On a successful save, it is no longer stunned.
