Forceful Smite (5e Spell)
From D&D Wiki
|Casting time:||1 bonus action|
|Duration:||Concentration, up to 1 minute|
The next time you hit a creature with a weapon attack before this spell ends, your weapon crackles with force, and the attack deals an extra 5d10 force damage to the target. Additionally, if this attack reduces the target to 50 hit points or fewer, it is stunned. The stunned target must make a Constitution saving throw at the end of each of its turns. On a successful save, the effect ends.
