Staggering Smite

4th-Level Enchantment Spell (Paladin)

Casting Time: Bonus Action, which you take immediately after hitting a creature with a melee weapon or an [[glossary:Unarmed Strike]]
Range: Self
Components: V
Duration: Instantaneous

As you hit the creature, your strike pierces both body and mind. The target takes an extra 4d6 Psychic damage from the attack, and the target must succeed on a Wisdom saving throw or have the Stunned condition until the end of your next turn.

At Higher Levels: When you cast this spell using a spell slot of 5th level, the extra damage increases by 1d6.
