Angel

Holy Sense. The Angel can detect any lie it hears without making a check. It can't make a lie itself.

Magic Resistance. The Angel has advantage on saving throws against spells and other magical effects.

Spellcasting. The Angel is a 7-level spellcaster. Its spellcasting ability is charisma (spell save DC 14, +5 to hit with spell attacks). The Angel has following cleric and wizard spells prepared:
At will: Aid, Feather Fall, Word of Radiance, Levitate
2/day each: Hold Person, Shatter                                                                                            1/day: Insect Plague

Multiattack. The angel makes two spear attacks.

Spear. Melee or Ranged Weapon Attack: +# to hit, reach # ft. or range 30/70 ft., 1 target. Hit: 8 (1d10 + 3) piercing damage plus 4 (1d4+2) radiant damage. 

Turn Unworthy. As an action, the Angel speaks a prayer censuring the unworthy. Each creature that is not a celestial or of their rank that can see or hear it within 30 feet of it must make a Wisdom saving throw (DC 14). If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.                                                     

A turned creature must spend its turns trying to move as far away from the Angel as it can, and it can’t willingly move to a space within 30 feet of it. It also can’t take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there’s nowhere to move, the creature can use the Dodge action.
