Beseech Atonement

You attempt to resolve a creature's misdeeds. You must make a Wisdom ( Insight) check against your spell save DC. On a success, the creature has its alignment changed from evil to good for the rest of the duration or until you end the spell. If it was already a good-aligned creature that became evil, it reverts back its original alignment. 

Additionally, if you succeed the check and the spell hasn't ended, you can use a bonus action to launch out a bolt of divine retribution. Make a ranged spell attack, on a hit, a creature takes 1d12 radiant damage.

at higher levels. casting this spell at 2nd level or higher increases the damage by 1d12 per level of the spell.
